To help organize my wrenches, because transporting wrenches in the plastic holder thingy that comes with them usually ends up with a broken wrench holder, I made a roll-up wrench holder from an old beat up pair of jeans.
Step 1: Things you need
3) A sewing machine or other form of fixing two pieces of fabric together
4) A ruler or measuring tape (optional)
5) Wrenches (optional, I guess you could leave it empty or put screw drivers in it)
6) Sharpie or some way to write on the jeans
