I used a food-safe modeling material (Silicone Plastique by makeyourownmolds.com) to make a mold of a heavy jacket zipper from the fabric store. I picked the jacket zipper because the teeth are bigger and I could get better detail. Now that I have the mold made, whenever I do a purse or wallet or diaper bag that needs a fondant zipper, I can make one in a few seconds.
I went to a baby shower last weekend and took a diaper bag cake. People were so impressed that it had a zipper it was like that was the only thing they focused on! LOL
Hi! I had the same problem when I made a purse cake, so I just bought a real zipper at JoAnn's and iced that onto the cake. I know some people are against non-edibles in there cakes, but I couldn't figure out any other way to do it. The picture is in my profile if you want to see it. I hope that helps some.
If you figure out another way to do it I'd love it if you'd (or others) share, I'd like to redo my purse cake sometime and see if I could do it better!
. . . you could do just as TooMuchCake suggests . . . except just use fondant/gumpaste for the "mold" . . . in other words, just make an impression with a real zipper into some fondant/gumpaste, let it dry, and then use the dried impression to make your final zipper . . .
. . . Think of things not as they are . . . but as they might be . . . Don't merely dream . . . but create!!!
Thanks, pinkbox. You can make an open zipper if you open the real zipper and make molds of each half. The Silicone Plastique molds are really great, because you can use them over and over again and they're ready whenever you are for those last-minute cakes that we all swear we'll never do but do anyway.
