I'm big on trying to use all my fabric. I have a clean trash can I keep beside my cutting table. After I cut fabric, I use it to scoot fabric into for real scrap quilts. Some people buy fabric to make scrap quilts. Not me! I use all my scraps from previous projects. It's like visiting old friends.
I also save my scrap batting. In the past I would use a needle and thread to sew my pieces of batting together. Now, I found this fusible product to iron on the seams. It works very well. It's faster than a needle and thread. My quilting machine likes it too.
