This is the back:
I did some ditch stitching on the outer blocks, and just straight stitches along the large squares.
My intention was to use the flannel backing in the self-binding style, but at the LAST minute, changed my mind and managed to eek out enough purple fabric from scraps.
So happy with that decision! See? Even the frogs are!
Oh boy! I can virtually cross it off my list... when I can get the code to work.
All done but the washing!
