It came from my wanting to use bits of linen, but not actually having quite enough. In fact, from the original linen pieces I could only have cut 5 or 6 of the necessary pieces. I like things to be orderly though (most of the time), so I decided to cut 4 pieces from each of 4 different neutral solids/near solids.
I think this block would make a really cool quilt. Maybe I'd make the pieces slightly bigger so I wouldn't need so many of them to get a decent size. Hmm...
The seams started to get bulky at the end, but not too terrible.
One hundred blocks to go. :)
