I will be sure to post my results of the Mod Podge stuff.
If you look closely at the dog's cheek you can see a spot where it looks like it wants to flake off and its a decent size piece too. I'll give the brush a try and go back over the spot with the laser to clean it up.
I want to get some round ones too and I did find some on Amazon but I can't recall the price. I'll see if I can find them again and post a link.
The ones I got had a few chips in the package which made me think that these can chip easily and I'm wondering if maybe adding a rubber protector around the edge would take away from the look of these.
I am finding this conversation very informative. Wondering if there should be threads devoted to specific materials.
That's probably not a bad idea.
