Was it something like the
Mosaic Quilt from Donna Jordans website?
This is the one I made one for a queen/king size bed -
My Mosaic Quilt. You layer the two 10" squares together and then cut them randomly, then sew them together with a piece of sashing and then line up two more cut them again - doing randomly again, not cutting them in even squares --- then sew again with another sashing strip, it makes it look like Mosaic tiles.
