This quilt is turning out beautifully. Sorry you've discovered too may HSTs! Did you use your AccuquiltGo to cut them? I love the accuracy of the Go for HSTs. I put it right on my sewing table, run the fabric pairs thru & immediately sew the HSTs. Makes them ALMOST fun to sew ~ ~ ~
And if you need an HST in a size you don't have, maybe you can figure out a different seam to use on one you DO have to make it the right size.
