Shop Tip #155

Instead of buying expensive drawer dividers and constraining myself to their dimensions, I like to line the bottom of some of my tool drawers with 1/8" Masonite so I can simply cut and glue in little wood strips to make dividers that fit the tools.  I don't plan out their locations, but simply start in the corners, working inward.  As a result, all my drawers end up with an irregular center section for new additions, small parts, or whatever.  The little strips work well and I can crack them off easily to rearrange the drawer anytime.
