I cut up all the old jeans and denim skirts for a pending "blue jean and flannel" beach quilt.
I cut up old clothes for either fabric for quilts or fabrics for the crazy quilt I'm going to make someday. (I've probably saved enough for about 10 of them by now, but I just can't seem to throw anything away.) I save the buttons from them too.
I save all the Altoid containers for pins and clips and heaven knows what. I like the idea of the Whitman's Samplers better though!! Yum, better contents and they retain some of that chocolate fragrance.
I save all the Joann's fat-quarter cardboards for making templates.
I've recycled two shoe organizers into storage - an open ended one for all the "rolled" stuff like stablizers and for cans of spray starch, and a closed end one for fabric stashes of small pieces.
I recycle TP and paper-towel rollers to hold cut binding, or to roll extra 'strips' to keep them organized by color, as well as for holding lace.
I recycled three old spice racks and jars from estate sales to hold beads and sequins, and bath salt jars for larger stashes of them. This will seem really neurotic - but most of the beads and sequins came from clothing picked up at thrift stores - and removed by me. Yep, I'm nutso, but it was actually fun to watch TV and "pick beads" as my DH called it. And, man-o-man are they cheaper to acquire that way. Naturally I cut up the rest of the outfit for crazy quilt fabric.
I guess I basically save and re-use everything I can! :) When I was growing up my Granny continually said "Use it up, wear it out, make it do, or do without" and I still hear her voice today.
