To make your own Mod Podge, mix equal parts white craft glue and water, and store in a lidded container. This formula results in a less shiny finish that camouflages brush strokes more easily than real Mod Podge, according to the Make Your Own Zone craft blog. Other blogs, such as The Artful Parent and Mod Podge Rocks, suggest that homemade Mod Podge mixtures do not work as well as real Mod Podge on many projects.
The idea of making homemade Mod Podge appeals to many crafters because white craft glue is far less expensive than store-bought Mod Podge, making the homemade version a cheaper alternative. Crafters who only require a small amount of Mod Podge can easily mix up a sufficient batch of the homemade version by measuring out smaller amounts of glue and water. In addition, a crafter who needs Mod Podge for an immediate use and does not have any on hand may decide to try the homemade version.
Homemade Mod Podge works well on projects that require an additional sealant, such as decoupage tile coasters, according to Make Your Own Zone. It is less successful when used on projects such as preserving autumn leaves, according to The Artful Parent. Mod Podge includes additional sealants and bonds more strongly than craft glue, making it a more durable decoupage medium.
