I have lots of polka dotted fabrics in my stash. They're great for kids' quilts. With the pastels I've made bunnies and with the stronger colors I've made pinwheels. If you have a lot of solids in a quilt, polka dots are great for sashings. I've also made several aprons as gifts using vintage fabric that has toasters all over it where I added a red and white polka dot ruffle.
