I will just discuss the scrap problem. I have a huge stash of beautiful fabric and get more donated to our charity group. I have a good friend that belongs to the same group. She spends hours sorting, cutting, etc scraps. She makes quilts out of them also. It takes a long time to make a top with itty bitty pieces.
I save only a couple of sizes I know I will actually use. 2 1/2 inch strips and 5 inch charms. I made 3 times as many quilts as her last year. I also work part time. She does not, I want to make quilts and not spend all this time processing scraps. Plus it is a big mess.
My sewing room is small and I just don't have room for all those different systems. I often gift a box of scraps to whoever wants them.
