Mini Love

As an Island Batik Ambassador the products featured in this post were given to me by Island Batik.

Do you like mini quilts?  Part two of Island Batik’s Ambassador February assignment was to make a mini quilt 24″ square or smaller.  I chose a simple block.

I used Island Batik Neutral Buttermilk & Mini Flower Carnation Pink, plus 2 fat quarters from  the Galentine Day Bundle, one red for the star points and another red for the border.

24 Block front

I decided to make 4 blocks.  Each block has a center square, 4 two color quarter square triangles for the star points and 4 half square triangles.  My block units are 2 1/2″ finished, and the block measures 7 1/2″ finished.  I decided to start with the half square triangles (HST).  For four blocks I would need 16 HST.  With my Tucker Trimmer I,  I can make two at a time.  Deb Tucker has a new Technique Sheet called “Eight at Once”.  This technique sheet has a chart that gives you the fabric requirements for oversized HST in 11 sizes.  For 16 – 2 1/2″ finished HST I would need two 7″ squares of the Mini Flower Carnation Pink and two 7″ squares of Neutral Buttermilk.

Using my Magic Wand, draw diagonal lines on the wrong side of the lightest fabric.  I also marked the vertical halfway mark & the horizontal halfway mark.

02 Mark

Stitch on all four diagonal lines only.

First trim  the vertical halfway mark & then the horizontal halfway mark.  Then trim in between the stitched diagonal lines. And, all at once you’ve got 8 HST.

06 Press

Press toward the pink.  Do you know that “what ever you are pressing toward…goes on top”?  That means lay your units with pink fabric on top.  Set your seams, then push over the pink fabric and press.

Lay your unit on the cutting mat.  We always trim our units to the cut size.  My units are 2 1/2″ finished, that means the cut size is 3″.  Find the whole circle on your Tucker Trimmer, align the 3″ diagonal line on the HST’s diagonal line and center it.  Trim up the right side and across the top.  Rotate the unit, align the just trimmed edge with the 3″ clean up line, again align the 3″ diagonal, trim up the right side and across the top.  If you are left-handed, position your unit to the left and the whole circle on your Tucker Trimmer would be positioned to the left also. You woud trim up the left side and across the top.

Now we will make our Quarter Square Triangles (QST).  I check the chart in my Tucker Trimmer instructions.  For 2 1/2″ finished units, my starter squares should be 4″.  For all four blocks I need Eight Red 4″ squares & Eight Pink 4″ squares.  Using my Magic wand I draw 2 diagonal lines on each pink square.  Layer one pink square with one red square aligning the raw edges.  Stitch on both diagonal lines and cut apart.

We are going to press toward the red , so lay your units red side up and press as before.  Divide your HST’s into two even piles.  Using your Magic Wand draw two diagonal lines as shown above on half of your HST’s.

Position one HST marked with the stitch lines with a HST without the stitching lines, right side together, and opposite colors facing each other.  Align and nest the center seams.

Stitch on the lines and cut apart.  Swirl the center as shown above and press.

Position the Tucker Trimmer over the pieced square.  Carefully align both the common diagonal and the 3″ size diagonal lines over the sewn seam lines.  Trim up the right side and across the top.  Rotate the unit, line up the Tucker trimmer again.  This time be sure to position both the diagonal lines and the outline of the square to the exact measurement of 3″, trim up the right side and across the top.

Cut four 3″ red squares for the block centers.  Lay out the block as shown above.

Stitch the units into rows, press the seam as shown.

Stitch the rows together and press as shown.

Make all four blocks.  I added sashing.  I cut two 1 1/2″ x 8″ strips and joined the two blocks on top row, and then the two blocks on the bottom row.  I cut three strips 1 1/2″ x 16 1/2″.  I joined the top row to the bottom row and added a strip on either side of the square.  Cut two strips 1 1/2″ x 18 1/2″ for the top and bottom of the square.  Note:  Always measure your blocks for accurate sashing measurements.  

From another Galentine Day fat quarter  I cut 3″ outer borders.  I finished it with my Hobbs Cotton Batting.  I stitched in the ditch and bound it with some Island Batik Neutral Buttermilk.  It was pieced & quilted with Aurifil Mako 50 thread.

This is a sweet simple quilt.  Reminds me of Forest Gump, “Life is like a box of chocolates, you never know what you’re going to get”, these blocks look like nicely wrapped chocolates.  Happy February!



BlockBuster 4 – Capital T Variation

This is a great block.  04 Capital T Variation requires the use of your Wing Clipper I, & Tucker Trimmer I.  You’ll be making flying geese, combination units and quarter square triangles.  The supply list shows 3 block options. I chose the first 3 color combination because I’m using some Kim Diehl fabric with a cream background for all my BlockBuster’s so I can make them into a cohesive quilt when I’m done.  You have 3 size choices.  I chose to make mine 12″ blocks with 4″ finished units.


All the instructions you need to make the units required for this block are with your Wing Clipper & Tucker Trimmer.  In both there are size charts that tell you what size to cut your starter squares depending on the finished or cut size of your units.  When making your block you will want to pay close attention to your color placement.


Remember when making your flying geese, your large square  becomes the body and small squares become the small triangles in your geese.  I have cut my starter squares to make 4 geese with a blue body and gold wings, and 4 geese with a gold body and blue wings.


On the backs of my small squares draw 2 diagonal lines using your Magic Wand.


Position two small squares on your large squares right sides together as shown above paying attention to your fabric choices.  Nudge your small squares in toward the center just a thread or two (about a 1/16″).  This will give more to trim off later.


Stitch using a scant 1/4″ seam allowance.


After stitching, cut apart.


Press toward the small triangles. Remember “what you are pressing toward – always goes on top”!


Position one small squares on the corners of the previously pieced units, nudging the squares away from the edges as before.


Stitch using a scant 1/4″ seam allowance. Cut apart.


Press toward the small triangles.



Position your flying geese unit pointed toward you (left handers see your Wing Clipper instructions).  Align the diagonal lines on your tool with the seams in your unit.  As you can see I’m am making a 2″x4″ finished flying geese, so the cut size is 2.5″x 4.5″.  Trim the two sides as shown.



Rotate your unit and reposition the Wing Clipper to align the previously trimmed edges and the X at the top with the intersection of the seams and trim again.


Repeat with all your flying geese units.  I now have two sets of 2.5″ x 4.5″ flying geese.

Combination Units:  after checking my size chart I know my starter squares for 4″ finished units are 5.5″.  I cut one gold, one blue and two background squares, all 5.5″.


Combination Units start by making half square triangles.

I grabed my Magic Wand and drew two diagonal lines on the back of one of my gold 5.5″ square.  Position the gold square on the blue with right sides together and align the edges.  Stitch on both lines using a scant 1/4″ seam allowance. and cut apart.


Press toward the dark triangle.  Grab your Magic Wand again and draw two diagonal ines on the back of both Half Square triangles.


Position each half square triangle on a 5.5″ background square, right sides together centering it.  Stitch using a scant 1/4″ seam allowance. Cut apart as shown above.



You now have 4 combination units.  Note: this process creates units that are “mirror images”.


Position the Tucker Trimmer over the unit, carefully aligning both diagonal lines with the stitched seams as shown and trim.


Rotate the unit and line up the Tucker Trimmer again.  This time be sure to position both diagonal lines and the outline of the square to the exact measurement desired and trim again.



Four beautifully trimmed combination units for the corners of our block.

Quarter Square Triangles:  Check your size chart.  These are 5.5″ starter squares.

On the back of my gold square I have again used my Magic wand to draw to diagonal stitching lines.

Position the gold square over the blue square, right sides together, aligning the edges.  Stitch using a scant 1/4″ seam allowance and cut apart.


Press toward the dark triangles. Using your Magic Wand Draw 2 diagonal lines on the back of one half square triangle.


Position the two half square triangles right sides together, making sure the colors are opposite each other (my gold is against the blue and vice versa) carefully nesting the seams as shown above.

Stitch using a scant 1/4″ seam allowance. Cut apart and press swirling the centers as shown above.


Position the Tucker Trimmer over the unit carefully aligning both diagonal lines over the seams lines of the unit.  Trim two sides as shown.


Rotate the unit and line up both diagonal lines again along with the outline of the unit to the exact measurement desired and trim. Only one quarter square triangle is needed for this block center.


Layout your units as shown above being careful of color placement.  Notice the body of my geese follow the colors in the quarter square triangle.  And the colors in the combination units are the same as the wings on the geese.


Stitch your geese together in pairs as shown above.


Stitch 3 units into a row as shown above.


This shows how I pressed the block.  The outside rows were press toward the combination units, while the center row was press toward the quarter square triangle.  This allows the rows to nest nicely.


The finished 12″ Capital T Variation block! I love It!

BlockBuster 1 – Ohio Star Variation

If you have been following Deb Tucker’s Studio 180 Design’s Facebook page then you know that Deb premiered their BlockBuster program series last January, which means they have a full year of exciting blocks to add to your quilting repertoire.

The Ohio Star is one of the most classic quilting blocks, and one that can be easily transformed by playing with the four cornerstone units.  Instead of the traditionally seen solid squares for the corners, they pieced two half square triangle units with two squares to make a more interesting variation.  Click here 01 Ohio Star Variation for the Supply list.  I all have the supply sheets for the BlockBusters on my page or you can go to Studio 180 Design

The supply sheet has a Cutting Chart giving you the option of making 6″, 12″ or 15″ finished blocks, and shows 3 different color ways.  I decided to make 12″ finished blocks.  I chose 4 colors for my block.  Color 1 is a light background.  Color 2 is my dark fabric for my star points.  Color 3 is my gold fabric and Color 4 is my red fabric.  it really helps to assign numbers to your fabric choices.


We will make four 3 color quarter square triangles using the instructions from your Tucker Trimmer I.  You will need 4 – 4.5″ unfinished quarter Square triangles for your block.  Check your Tucker Trimmer instructions, there is a chart that based on your finished or unfinished size unit tells you what size your starter squares should be.  You will need 1 – 5.5″ (color 1) background square,  2 – 5.5″ (Color 2) black squares & 1 – 5.5″ (color 3) Gold square .


We  start by making half square triangles.  Position: I placed my background square and my gold square on my 2 dark squares.  Placing my “Magic Wand” diagonally on the squares I drew a line on both sides of the wand.  I sewed on the lines and then cut them apart as shown below.

I then pressed them towards the dark triangle.  When ever you are pressing, remember “whatever you are pressing toward, goes on top”!


Using your Magic Wand, draw diagonal lines on the back of 2 half square triangles.


Position your half square triangles right sides together making sure the dark triangles are opposite each other and that the seams are nicely nested.


Sew on the drawn lines and cut apart.

Swirl the centers and press making sure all the seams completely open.

Trim using your Tucker Trimmer. The cut size of the unit is 4.5″, find the half circle on you Tucker Trimmer and the diagonal 4.5″ line. Using the 4.5″ line and the common diagonal line center it on your unit and trim 2 sides.  Then rotate your unit centering as before but also using the 2 trimmed sides and trim again.  You now have 4 – 3 color quarter square triangles that will be the star points for your Ohio Star.

Make the corner units that are made up of 8 – 2.5″ unfinished half square triangles and 8 – 2.5″ squares (4 from our background fabric and 4 from your color 4 fabric).  We start by checking our chart to find for 2.5″ unfinished half square triangles we cut 4 – 3″ starter squares of both our dark and background fabric. Again using our Magic Wand draw diagonal lines on the back of the background fabric, position and sew on the lines.

Cut apart and press toward the dark triangles. As before trim to 2.5″ using your Tucker Trimmer.

Layout 2 half square triangles, 1 – 2.5″ background square and 1 – 2.5″ square from Color 4 as shown below.  Sew 1 half square triangle to a background square and 1 half square triangle to a color 4 square.  Press toward the square fabric. Place right sides together and nesting the seams and sew together.  You can press the seam to one side or, I chose to press it open to lessen bulk.

Cut 1 – 4.5″ center square  and lay out your block units as shown below:


Sew units together in 3 sections.  Press the side sections toward the corner units and the center section toward the center square so the seams nest nicely.

Join the 3 sections to make your Ohio Star Variation.

Tucker University.  I’m getting ready to use this great program at the end of the month at Stash Away Quilt Shop in Rome, NY.  Tucker University was created based on the product line offered by Deb Tucker’s Studio 180 Design (S180) tools and Technique Sheets.  Deb Tucker and her team continue to introduce news tools as well as techniques to expand the use of the tools.

The Tucker University curriculum was written with the busy shop owner and/or S180 Certified Instructors (CI) in mind.  This curriculum allows the shop owner or S180 CI to use a pre-designed lesson plan to offer technique building classes to their customers.  The lesson plans and student handouts have been prepared for the instructor and are ready for use.  The preparation time is now minimal.

These lesson plans allows the student to learn to use the tool without having to make an entire quilt.  In the first lesson “Tucker Trimmer I & Shaded Four Patch” students will make half square triangles and  2 & 3 color combination Units.


Half Square Triangle


Combination Units

Students will also learn to make 2, 3, & 4 color Quarter Square Triangles.




Quarter Square Triangles


Last but not least, student will also learn to make the Shaded Four Patch Unit.



Shaded Four Patch










With the Tucker Trimmer alone, a quilter has 33 opportunities to create precise units.  These units are often referred to as basic units, therefore they must be precise to fit nicely with more advanced units.
