I use the large plastic salad containers to hold things and I bought a fruit & dip tray at Sam's & reuse it for holding my sewing machine feet & other things. It has little compartments that held the dip & fruit, and a lid. I like that they're see through.
Recently, my husband used his dremel tool to open up one of my fmq feet. It was a clear plastic ring, but I couldn't really see the line that I wanted to follow. Now it is an open toe fmq foot (shaped sort of like a C.) and it works wonderfully.
My Dad used to do some upholstery. He recently gave me some rolls of fabric. I took the fabric off the rolls & plan to use the rolls with basting quilts. I've seen on the web somewhere a woman basting quilts with 3 flat boards and thought maybe the rolls might work the same. Haven't tried it yet, but it's worth a shot.
