This may be overkill, but I have a small pillow insert that I've covered with flannel, and I use that for a pin cushion when I need a lot of pins. It's flat, so it sits almost anywhere, and I put a loop on I can also choose to hang it from something. I kept tipping over the plastic boxes with the pins in, and that made quite a mess to clean up. That's when I made my "pillow pincushion." Love it!
