What is a safe finish/sealer to use to make a set of decoupaged baby blocks drool-proof?
I know that Mod-Podge is water soluble, so it could make for a pretty gummy block after a 6 month old attacks it. I'll need to make it water proof somehow.
On reading a particular Instructable on these blocks, the author said to use a non-toxic acrylic sealer. I could not find such a sealer (or none stated "non-toxic") at the craft-store.
What is a safe brand or alternative to use? OR. . . Mod-Podge aside, what kind of method would YOU use to make these said set of baby-safe blocks?
I thank you, kindly!
