I use a cool whip container with a slot cut in the lid to keep my rolled up binding neat, then pull it through the slot when ready to use.
I use brown paper grocery bags to iron on when working with fusibles, then just toss when finished. Also good for pattern making.
DH's cigar boxes make great storage containers for pens, pencils, etc. They stack well and are sturdy.
Love reading everyone's ideas, keep them coming!
