Oh, now where is Crafty Julia? I think she would love this challenge.
As for me, I have tons of scraps and try to use them often rather than cut up a new piece of paper. Of course, if I use a 5" square piece of scrap, then I still end up with little bits of scrap, so the stash doesn't seem to decrease. My friend Sue and I challenge each other about how small a scrap piece has to be before we throw it away. We do keep inch size pieces, 1/4 inch strips, and sometimes the little shapes left over from punches and die cuts.
Now to see if I can make something for this challenge. Be back later.
