Sewing thread used to be rolled on these beautiful reels. Too bad they are now mostly made out of plastic. I was lucky to find these old wooden beauties in a fleamarket and made a necklace and some magnets out of them. Both are very simple to do. You can get round magnets from the stores selling craft supplies and for the necklace you only need a strong string.
So, keep your eyes open when visiting a fleamarket...
