I found a pattern a couple of weeks ago that was done in stone looking fabric with about 4 or 5 values of the same basic color. It was squares in squares then cut on the diagonal and sewn back together with one side inverted colors from the other. Lights and darks. It made it look like carved tiles. There were three different size blocks but all were made the same way. I've been unable to find it since and I'd really like to order it. It is a very geometric pattern along the same lines as some of the Bella mosaic quilts but I've looked there and can't find it.
