Mod Podge for gluing and protecting SoulCollage® cards and tempera paintings on paper. Instead of rubber cement, which is handy and quick, but toxic, and spray acrylic or varnish, also toxic, Mod Podge does it all for me, is cheaper and safer.
This White Tara (or Sitatara) SoulCollage® image is the seventh card I've used Mod Podge on. The surface is sturdy, safe and not tacky so cards won't stick together in a pile. I am indeed feeling green and environmentally pleased with myself as well as creative.
Now. Off to the garden . . .
