Oh I never thought of using mod podge instead of paste for pare mache! I may use that when I do my artist in residency week in september! I am going to have some of the kids use paper mache to sculpt their heads for the puppets.

Well it was a bit of a "mistake" in a way on my part.  I wanted to do a project and could not find wheat paste at a store near me and did not want to drive out to where I knew I could get it. I saw the ModPodge at Hobby Lobby and thought "What the heck." and decided to give it a try. Even when I use wheat paste I add white glue to the mix so figured it could not be that different.

I've used clear finger nail polish in the past to seal my eyes.

@Shawn, I made a mistake and used clear polish on a foam golf ball.  I spray painted it white, painted on the pupil and then covered it in clear nail polish.  It cracked!  It would be a good effect on a goulish character but I was going for a little boy.  I don't know if it would crack on a regular ping-pong ball or not, or maybe it was just the brand, or the combo of the foam/spray paint.  Anyway, one must experiment to find what works.  That's half the fun!

Ahh yes... that makes sense Angel.  Finger nail polish would not be flexible and I have always used it on a solid base.  For foam ModPodge may be a better option since it has a bit more flexibility.

You are so right.... what works for one thing may not work for another.  It is all one big experiment!
