I like making sampler quilts. Not only do you have variety so you don't get bored doing the same thing over and over again but each block presents a new challenge and skill learned. Eleanor Burns has some sampler quilt books which are easy to follow. With each quilt I make I try to do something different - a new block or new technique to a block I've made before. This way I am broadening my skill base while at the same time ending up with a nice quilt, table topper or something else that is useful.
