Love2craft: I understand your dilemma. I also want to make these cute little storage pods. I found a good source for the Atkinson zippers in many colors (which are YKK) and are made for this type purpose. You can also buy a bag of extra pulls in assorted colors from the same source. Right now the 14" zippers are only $.99 and shipping is reasonable. The pulls are in a bag of 30 for $8.49. (Although to use this many pulls you would have to make 60 pods! Lol)
