I have this problem when dealing with scraps but I know why. I have a tendency to buy a bolt or almost a bolt of neutral off white and use it in lots of projects so I don't have scraps accumulate but I do have scraps of all the primary fabrics I use. I am trying to decide how to cut up a pretty large quantity of medium and dark scraps. I keep putting it off because I am afraid that if I cut 2 inch squares I will want 2.5 inch squares. But I know that I will have enough light fabric because of the large quantity purchase. So many scrappy quilts I seem attracted to have lots of medium and dark scraps and just one light.
