I have no idea how long I could go or how many quilts I could make. I don't have any large pieces of fabric, mostly fat quarters, but lot's of them. I usually have to buy a background fabric, or sashing, and always backing, even if I don't buy new "main" fabrics. I also don't have any batting, except a couple of small pieces. I never have bought alot of patterns or notions, I can usually make do, and I like to create my own patterns. I have 5 rotary blades, and that is the most I have ever had at one time.
