It's one of my favorite blocks because it's easy to handle, easy to sew, and I can churn out lots and lots of them in a very short time. Here's my method:
|Stack 2 squares right sides together.|
|Stich 1/4 inch from both sides of the fold.|
|Chain stitching makes fast work of many blocks.|
|Cut apart on the fold.|
The reason this block is so popular is that it can be arranged into hundreds of designs. Just by turning these 4 half square triangles I end up with very different designs. And if I added in squares or any other basic quilt shapes... well... the possibilities really are endless.
The half triangle square - an amazing block!
