I love to deconstruct old bags for their webbing straps and any usable zippers. They get stored for future bags and sometimes these pieces of re-enforcement inspire the final look. However I realized some of this could be a craft supply hoarding problem.
I replaced my shower curtain liner the other day. Instead of throwing out the old liner, I dried it and folded it for a drop cloth and cut the magnets out of the little pockets in the bottom. The magnets are now bare on my fridge, which doesn't need any more magnets. The drop cloth is now in my pile of work supplies in my linen closet.
I'm not sure at this point if I'm resourceful and crafty or just can't throw things out.
