Measurements for new way to make HST?
I know there's a new way to make HST but I don't know how you figure out the measurements. I know you cut out two squares of equal size and put RST and then sew 1/4" around the outside of the block and cut it into 4 triangles and it give you 4 HST. But if you want the end result to be 2 1/2", how big of pieces of fabric should I cut? Is there a way to figure any size of HST out?
