Take the "flat" trays, from yor store bought plants, and turn them into drawer compartments.
Save your small onion sacks. Put small blocks in them, for the
children. also they work good for hanging cedar blocks in your closet.
Toilet paper rollers can be used to hold short dowells, or short flat stock.
Of corse there is the old stand-by of coffee cans, for small parts holders
Soap that is too small to use, can be used for lubrication for "wood-on-wood" slides. Short candles can be used also.
If you get a glue joint that is just a little lose, add a scrap
of news paper to tighten the joint. (it takes some practice to prevent from making a mess,but mistakes are 90% of the learning process!)
Use an old fish net to hold your coiled extension cords.
The old silver ware tray from the kitchen works good to hold bits and drivers, in a drawer.
A soup can by the work bench is a good place for the pencils that you can never find.
Can't afford a sanding pad, here is a temporary fix. at the carpet stores they usualy have scrap carpet padding. and in most cases you can get this for next to nothing. (make sure you get enough to make pads for your feet as well)
Ok that is enough for now. enjoy your work shop and have fun!!
