Have you tried looking through quilt magazines and books for designs you like, no matter what colors are used? I am working on two wall quilts of Christmas prints, both of which were shown in browns in the library books where I found them. Several larger pieces went into pillowcases for a craft sale. The next one I'm going to piece of Christmas scraps is a "scrappy star", which alternates hourglass and plain squares with the colors laid out so you see stars that share points between them.
