My wife drags me to Winders Fabrics in Homosassa when she's in the sewing or crafting mood. She normally finds what she wants there at a price significantly lower than the prices at Joanns.
There's also the Fabric-Warehouse in Lakeland that she wants to go to.
If I were you I'd call them up and see if they carry the types of fabrics or supplies that you desire first.
