I'm sure having fun with the Sweetpea Pods by Lazy Girl Designs.
http://www.lazygirldesigns.com/bag-d...pper-technique If you start with a 9" square instead of a 10" square, you can use the 14" zippers. If you can find zipper by the yard with seperate zipper pulls, it's pretty cheap.
I figured out that if you made 40 of them, used a layer cake, 9 yds of zipper by the yard, with 40 zipper pulls, that would be about 40 + 13.50 + 10.00 = 63.50 / 40 = 1.59 each.
