Try quiltville.com. Bonnie Hunter has a scrap saver system. As you cut for a quilt and you have left overs, you cut them it to the sizes most used. For her "Bargan Basement" quilt in her book, I cut 9 1/2 by 3 1/2 for the largest piece. Then cut the next largest, 5 x 3 1/3 then 3 1/2 squares, and 3 1/2 by 2, and so on. I put them into separate baggies and then I will have all the pieces ready to start sewing... I even have 1 1/2 inch squares and strips to make 3 1/2 inch blocks of 9 patches or strips to fill in. She says why use a plain block when you have leftover 3 1/2 inch or I just make them as I go with scraps.. It uses even the smallest pieces.
She makes many scrap quilts and has many on her web site free. Or there is always her "Crumb Quilts". I took a class with her at Hershey this past summer. I think she will be there again in 2012, but not 2011, she is booked already. Maybe you can catch her at a guild meeting. Check her web site for her schedule.
