It can be found here
As most crafters know it's one of the more expensive glue/glaze's but now you can make your own by just using pva glue and water.
It has a matt finish but if you want it shiny you can add some glaze to the mixture.
Obviously it's not exactly the same as mod podge but it is pretty close, you can use it for all of the same projects the only difference really is that it needs at least two coats to make it waterproof.
This is good stuff, I've even used it to cover wooden boxes with magazine pages, so what are you waiting for? go and make some and start your next project :)
