I sometimes keep the scraps together in a zip lock bag then put the bag in one of my bins that are organized by color. I recently saw on one of Karen Brown's videos (Just Get it Done Quilts), that she will immediately makes a secondary quilt from the scraps if there are enough left overs from the first quilt. This by-passes storage of at least some of the scraps. I just finished a quilt this weekend and have plenty of scraps to give this a try. We will see if it is successful. I do have a long list of projects with deadlines that need attention. Do I have time to add another? We shall see.
