I buy from Joann and Hobby Lobby but most of my fabrics I get from
Fabric - Discount Fabric - Apparel Fabric - Home Decor Fabric - Quilting Fabric - Save up to 70% - Fabric.com. If I just want to make one dress or outfit I buy fat quarters and most of those I get from Etsy and there are tons of sellers on there. I have ordered from this seller most and her fabric is so nice and she ships very fast
