Mod Podge is a brand name for a gel medium used in découpage craft projects. The sticky substance acts as a glue, sealer and finish. With Mod Podge, you only need one product to affix cutouts to a surface, cover the cutouts with another coat, seal and finish. Not all crafters use Mod Podge; some alter common products to produce a similar result.
Squeeze 240 ml (3/4 cup) white glue (like Elmer's Glue) into a container.
Add 60 ml (1/4 cup) water.
Stir with a wooden ice cream stick until the mixture is smooth and well blended. Store in an airtight container.
Adjust the thickness of the mixture by adding or reducing the amount of water added to the white glue. The mixture will last for weeks, providing it is stored in an airtight container. Discard if it dries out or turns a different colour.
