Those are the cutest cards I've ever seen, lol! The ones with the pigs! I don't have such wasted cards, so I'm using metal box of chocolates to store my threads
I like the idea of recycling on whatever is possible, just that... with my stitching stuff, so... hygienic, that I always avoid to put them on places or close to things that are in public use. Sorry, I guess I am too touchy about it.
