I often find myself under my car doing stuff. And while doing said stuff, I often find myself putting my tools on my chest. Why? Because it is a strain reaching back behind my head or across from myself and i don't have to go very far to get them. No forgetting where I put it too if it is sitting on my man bosom. Only problem is they fall off sometimes, like a lot.
So I got the idea to cram some magnets in a work shirt on my right side (since I am right handed). Personal solution to make my life friggin' easier.
I basically added a handy dandy pocket which has a magnet covered insert slid into it. The insert is removable so that the shirt can be rung out in the wash without sticking to the washer and everything else in there. The insert is made from oil/water resistant/proof stuff so that you taking a spill under the car doesn't ruin it. I chose a semi-rigid plastic for the insert to keep the magnets from folding up the shirt and sticking it together.
