Two using HSTs.
Japanese + & X, and Granny Squares.
Disappearing Nine Patch.
This one measures out at 20" square.
I used men's shirts for the backs.
What the backs look like. Each one has a pocket for putting secrets.
I don't have any 18" or 20" pillow forms, so these are flat.
The string quilt is one of the first I made. I think it goes well with the pillow-covers.
May your bobbins always be full,
