They are fun and another 'excuse' to make something quilted. Actually I don't need an excuse-I really enjoy making little quilts. Sometimes I make them (or potholders) just to have something on hand to give away. They aren't any more silly than tissue box covers, little boxes or lots of other things. They are just fun and are practical. They also give you an excuse to practice your FMQ skills. Keep making them and let the cups rest where they may.
