I've done a couple that I have used the same pattern on, with different fabrics. But mostly I like trying new things so that I don't get bored with it. I generally have more than one project going at a time any way. Like crocheting, and a quilt, and a cross stitch picture, then I can pick up which ever one I'm in the mood for. Takes a little longer to get things finished but I don't get bored.
