I've cut 6 six inch squares of 21 different red or blue fabrics, and 126 six inch squares of Kona White. I'd decided to make HST; I'd matched a color square with a white square and sewn opposite sides together, when a brilliant idea popped in my head. Why not make some four patch blocks, too.
I took one from each group and those will be the four patch blocks, I'm using the Magic Four Patch Tutorial. I'm not sure, yet, what I'll do with them, but I'm making them anyway.
Now, I'll sew opposing sides again, before slicing each block to end up with 42 four patch blocks and 420 HSTs. I don't have a firm plan, obviously, so I'll just see what happens when I start laying them out.
May your bobbins always be full,
