I had started this some years ago too. I haven't bought any fabric in years. I work on collections. For instance, I am using up the Aunt Gracie line and have made four quilts out of that stash already including two king sizes. Check my threads to see lol. I even made a point of using the AG scraps to really finish off this line. The Diamond Star

I am currently working on, is all out of my stash. I don't even have to buy backing or binding as I am using what I have.
I know it's hard not to buy fabric but if you don't go in the store, you won't be tempted.
