When you are sewing, chances are you're going to drop some straight pins and/or needles at some point. It's basically inevitable. And have you ever stepped on one? Even in shoes, it's no picnic, and barefooted, I don't even want to tell you how bad that is, and I hope you never have to find out.
An easy fix is to get a magnetic "pin cushion." Just hover over where you may have dropped needles, and they will be pulled into the pin cushion. It even works if you've dropped them on carpet. It's much easier than trying to pick up each pin separately and may even pick up those pesky pins that you don't even see! Save your feet and get a magnetic pin holder.
