Here’s something from Grandma’s penny-wise idea jar (not that I ever saw my Grandma do this, but I know it used to be done):

When you slice your homemade bread, or cut the crusts off for your picky eaters, save all those little bits for bread crumbs.  Because I have an old-fashioned under-counter breadboard–love it!–I cut my bread on there, tuck the board back into place under the countertop, and let the crumbs lie until the next time I use the board.  By then, they’re dried out and I can put them in a little glass jar I keep handy near the cutting area.

I set the cut-off crusts out on a plate until they dry and then stick them in the jar too.  When I need bread crumbs for a recipe, I just grind ‘em up and use them.  I also stick the little bits of crackers at the bottom of a bag in the jar too.
