Joann Fabrics has everything that a new or experienced arts and crafter could want. I took my niece to a class to learn to make an apron. I thought the price was really high for what they made, but she learned a good techniques.
An alternative for beginners is the Frock Chop at Springs Preserve. For about half the price the kids learn how to upcycle their own t-shirts and jeans and learn about the environment. The best part is that there is no sewing machine required.
