The plastic containers that cakes come in are perfect for putting fabric & pattern in for your planned project, plus strips & 2, 3, &4 inch scrap blocks. They stack nicely & you can see what is in them.
Plastic baby food containers with the lids for pins or other small things. I keep my bent pasting pins in them.
Rubber shelf liner under my foot peddle & hand size pieces for controlling quilt instead of quilting gloves. I hate gloves of any kind & these are easy to move around & you don't have to keep putting on & taking off the gloves.
