Decided to re-line my rollaround toolboxes with cardboard based on my brother's suggestion.

Need something to wick away moisture and oil from the tools while protecting the drawers themselves. The mesh liners are good to keep tools from sliding around but just using the mesh crap alone creates pockets of dirt and grease.

He uses sheets of cardboard in his cabinets with the mesh liners on top. Cardboard is easily replaced when soaked and the mesh lets the crap drip down off of the tools. Corregated cardboard appears to have enough absorbance as not to go through to the drawer itself unless you tip over a can of stuff. Can also put down some stuff under the cardboard to absorb moisture or just throw in one of those silica packets that come in a variety of store packaged stuff (shoes, computers, etc).

Thought I'd pass along this helpful tip to others and ask this simple question: where can I get some decent sheets of cardboard that are (my drawer sizes) 18"x30" ? Need at least 18 of them. Was looking around for some used boxes to cut up from local businesses but nearly all topped out at 24" in size. Would rather not try to piece these sheets together which would result in bumps or gaps. Are there any craft-type stores that sell sheets of cardboard cheap? Am trying to avoid going to uHaul and buying overpriced moving boxes.
