There are tons of great fat quarter quilt patterns out there. I have used several of them. I like to put as many fabrics into a quilt I can which gives it somewhat of a scrappy look. I have used matching fabrics in borders as well as contrasting fabrics that were not in the quilt. Many of the patterns that call for fat quarters can also be cut from yardage. If I have say, a piece of 1&1/4 yards I'll cut the block pieces from the 1/4 yardage if possible than I have a yard left to use in borders or binding. Other times if I have a half yard piece I will turn it into 2 fat quarters for 2 different quilts.
