Tute for HST
Okay, here is the cheat sheet. Be aware that you should always try a sample with your machine before cutting massive amounts. I used 1/4" seam throughout. And, they do have bias edges, so I finger pressed and finished up with some Mary Ellen Best Press (or any sizing will work) after they were all cut.
Each pair of the following sized squares will yield 4 HST:
2” square=1” HST
2 ½”=1 ½”
3 ½”= 2”
4"= 2 ½”
5”=3”
5 ½=3 ½”
6”=4”
7”=4 ½”
8”=5”
8 ½”=5 ½”
9”=6”
10”=7”
