Half Square Triangles

They are also commonly called “HST’s”.

There are many different methods to making half square triangles. Every quilter has their favourite. Try a few different ones and you will find one that you like.

Quarter Square Triangles

Quarter square triangles are made by cutting squares into four on the diagonals. They can be stitched back together into units with two or four different fabrics.
