4, 5 or 6'' Zippers

[breelee.livejournal.com]

I would like to make some coin purses, but I can't find zippers that are smaller than 7 inches.  I know I can cut larger sized zippers down to size, but I really like the finished look with the metal end.  I've been all over my area and the Internet looking for smaller zippers, but I haven't had any luck.  Someone suggested doll zippers, but I haven't been able to find those either.  Please help!  Do you know where I can find them???  Thanks!
