Last week I showed you my Big Star Quilt made from layer cakes. In that lesson I used the Easy Half Square Triangle method for the first time. It was easy but I wanted to be able to apply it to more sizes. I saw a post that stated if you add 3.5″ to whatever size you wanted that would do the trick. But I didn’t find that to be exactly accurate.

When I sewed two 5″ squares together and cut them apart diagonally, I ended up with a 3″ half square triangle (HST). So that meant from 5″ squares I could get 1.5″ & 2.5″ HST.

When I sewed two 7″ squares together and cut them apart diagonally, I ended up with a 4.5″ HST. So that meant from 7″ squares I could get 3.5″ & 4.5″ HST.

When I sewed two 9″ squares together and cut them apart diagonally, I ended up with a 6″ HST. So that meant from 9″ squares I could get 5.5″ HST.

When I sewed two 10″ squares together and cut them apart diagonally, I ended up with a 6.75″ HST. So that meant from 10″ squares I could get 6.5 HST.

Choose your size square and sew all around the outside edges using a 1/4″ seam allowance.

Cut diagonally,

Cut diagonally again

You now have 4 half square triangles.

6.75″, 6″, 4.5″, 3″ HST

Pillows A-La-ModeGreat tutorial! I’ve never seen that Wizard of Oz fabric! Being from Kansas, I’m intrigued . . . π

ifthesethreadscouldtalkPost authorYou haven’t ??? I am a Wizard of Oz freak. I must have 6 tubs of Wizard of Oz fabric. It was made by Quilting Treasures I think, it came out in 2008. There is not much out there now.

Pillows A-La-ModeThanks for the info! I’ll do some checking to see what I can find. π

NaiaI understand the cutting/sewing part but I’m completely lost on the math stuff up top.

ifthesethreadscouldtalkPost authorIt means, from 5″ squares you get 3″ half square triangles that you can square up to be either 1.5″ or 2.5″ half square triangles

7″ squares produce 4.5″ half square triangles, so you can also square them up to get 3.5″ HST

Etc, etc. does that help?

NaiaI guess I feel a little stupid. If you have a 5″ square, sew all the way around it, cut it up – wouldn’t you have 2.5″ HSTs, not 3″?

I get the pictures – not the math. I’m a practical application person so that would make sense. I see and can recreate. I can’t read it and understand it. Sets me apart from the ladies in the local quilt guild, too.

ifthesethreadscouldtalkPost authorIf you take a 5″ square and measure across diagonally, it will measure 7″ . You should take two scraps, cut them into 5″ squares, sew right sides together all around the edges. Then cut them diagonally. You will understand then. I firmly believe there are no stupid questions.

NaiaOH! Measuring diagonal!

…. right?

ifthesethreadscouldtalkPost authorYou betcha

NaiaHey – do you feel like tackling this one and explaining it? π

I’ve been staring at it all day.

ifthesethreadscouldtalkPost authorThere are a lot of pieces, but it looks like they are mostly half square triangles . If not they should be.

NaiaPart of what I read was that they were trying to get rid of so many sewn pieces and do it in bigger sections.

ifthesethreadscouldtalkPost authorLooks like she gives you great directions, just take it one step at a time.
