I have also been working on some new zippityDooDahs using very old,old zippers. These are my favourites as the metal teeth on them are very fine and I can achieve great petal shapes. The problem being that these older zippers are hard to find, plus the tapes are a little harder to get the needle through so my fingers get a little sore! I really like the yellow one ( and I'm not a big fan of yellow usually) it has photographed as well as I hoped, m ight have to give it another go. The pink/red one was inspired by poinsettia flowers,and  the red one ; hibiscus.
