Modge Podge is really expensive. Like most things, you are paying for the brand name, marketing, packaging etc etc. If you are big into up cycling and crafting, chances are you are going to need to use it at some stage, so why not make your own. It is purely glue and water mixed together. Kerryanne at Shabby Art Boutique has written a lovely piece here on exactly how to make it, and what quantities to use for slightly different effects. That and she makes her own little labels for her bottles that I think are too pretty so I wanted a pic on my blog.
