This is more what I had in mind!
There was just enough fabric in that striped shirt to make the blocks, and just enough of the close-enough-to-muslin fabric I grabbed for the sashing and borders. After doing the math to see how wide I could make the pieces, I don't think I had more than an inch of it left!
I decided not to do my usual meandering for this one, and I'm not nearly as happy with the feel of the finished quilt. It's too puffy for my taste, but it wasn't for me anyway.
