So let's share the OPPOSITE - Least/Never used supplies
Yeah, I have a few. Reading the other thread, I also have a ton of Martha Stewart Punches, around the page and the ones you could tile to punch a whole sheet. Have barely used them, although I have used the edge ones a bit.
I never really liked or used decorative scissors - except the postage stamp and the scallop ones.
Recently dragged out a bunch of Making Memories paints. Not lasted very well - those crap metal tops let the air in - threw them all away - but the hinged black lids at least kept some of them still liquid.
Pigment ink - rarely used that
Bloody eyelets. I SO prefer the ease of brads so I have amassed quite a stash of them as they ALWAYS came in the couple of scrap-kits I subscribed to.
So many more but I have to leave some for others to claim!
