When you reorganize your basement or garage, buy yourself a number of cardboard boxes all the same size instead of scrounging various-sized used boxes. This way they will all have covers and you can stack them neatly. Mark each box with a big letter and number, like A-1, A-2, etc., on all four sides and top. Use a three-ring binder to write down the box number and its contents.
No matter what size your workshop is, there are some basic safety tools you should not be without. A smoke alarm, fire extinguisher, safety goggles, and first aid kit are absolute must-haves. Plus, all of your electrical outlets should be equipped with ground-fault circuit interrupters. If an emergency ever should ever arise, a telephone should be nearby to enable you to call for help.
