I am a self-proclaimed Deb Tucker Groupie! I love the Rapid Fire Lemoyne Star Ruler – NO “Y” SEAMS. This post is not meant to replace Deb Tuckers instructions. It is meant to encourage you try her ruler. The instructions that come with the ruler are very detailed and easy to follow, and also include instructions for Left handed people. You can purchase Deb Tucker products from their web page at
Each block requires two background strips and two star point strips. I cut two background strips the width of fabric and mark one “A” and One “B” at the top.
Cut two star point strips. Place a star strip on Strip “A” right sides together down the same distance as the background strip is wide. Do the same with Strip “B” as shown below. Sew both with 1/4″ seam allowance. Notice you are sewing strip “A” on the right side and strip “B” on the left side of the strip.
Press star strip “A” toward the background strip. Press star strip “B” toward the star strip.
Place strip “A” & “B” right sides together with strip “B” on the bottom, nesting the long seams.
Line the Rapid Fire Lemoyne Star Ruler edge along the stitching line and bumping another ruler against the angled edge. This will give you your 45 degree angle. Cut off the staggered end and discard.
Continue making cuts the same width as your Star Point Strips. In this picture my star point strips are 3 1/4″ wide, so I continue to cut 3 1/4″ wide units.
Second cuts. Position the ruler edge at the tip of the star strip and trim straight up.
This shows the parts placement to 1/4 quarter of your block. With right side together center the triangle you just cut off on the side of the unit and sew together.
Place the two units in front of you with the star points facing toward you. “A” is on the right and “B” is on the left. Press “A” toward the star point and press “B” toward the background.
Place the unit right side up pointing the diamond toward 2:00 (for ease in cutting both directions). As you can see in this picture I did not position it correctly. Align the desired block size lines with the sewn seam lines. Trim along both sides of the ruler.
Place two units together nesting the seam and starting at the star point and sew together.
Join the quarters together and sew, then sew the halfs together. Press seams open.
