Thanks everyone for the kind words.
Yes, my first thought was, "Oh no, wrong seam width," but I double checked and my 1/4" foot is right on the money.
The small blocks (168 of 'em) are one batik 3" x 5" with a black 1 1/2" strip on each side.
Then four are assembled into a block.
I'm sure I'll figure out some way to square all of the little buggers up after I stopped being aggravated!
