I haven't had a lot of time to crop, so I've been sneaking a few minutes here and there to do sketches for layouts that I can use later. It's working. When I've got time to sit down and crop, I'm working through the sketches and I'm getting a lot done more quickly.
I'm not keeping a lot of scraps these days. I have yet to think, "That scrap of yellow print that I threw away four months ago would have gone perfectly with this layout. Why didn't I keep it?" Nor do I dig through my scraps and find the perfect piece of anything to go with a layout that I'm needing 'just a little more' for. I don't miss the ones that I throw away and I don't use the ones that I keep. Ummm, why keep them?
