In case you were thinking of doing an image transfer onto balsa wood using Mod Podge, I tested three different methods for you.
Method One: Inkjet print coated with Elmers; Balsa coated with Mod Podge. Smoosh together and leave overnight.
Result: Worked fine but it didn’t look quite right until it was dry, so I didn’t realize it turned out until a few days later. Also, the Elmers warps the wood. The colors are bright and the glue is glossy.
Method Two: Inkjet print coated with Mod Podge. Smoosh to balsa and leave overnight.
Method Three: Laserjet print (from a photocopy at Staples) coated with Mod Podge. Smoosh to balsa and leave overnight.
Result: Worked fine. Colors are less bright than with Elmers. Matte finish. No warping. Image seems to be more a part of the wood rather than something that sits on top of it.
