Copycat - I did a scrappy binding with 4" strips on the bias. I really liked how it turned out. I wasn't sure how much I'd end up with, and still have about 7 yards of it for another project (I guess I made a bit more than I needed).
I cut the strips, sewed them together, cut on the bias and then attached those strips together into one long one.
This is the quilt it went on - made from fabric I got from my sister, each 5" block is a different one. The binding was all from the different solids she had.
