Carbouns from Sun and Moon and painted on the back (flat) side of the glass. Once it was dry I placed a heavy coat of Diamond Glaze Dimensional Adhesive on the back and added a magnet while it was still wet. The magnet dries right in place!
Flip the magnet over and clean up the front of the glass with some 91% isopopyl alcohol (very inexpensive compared to the Blending solution), and you are done!
I have a few more in the works right now - I'll be adding more colors - so much fun and they are so handy! I don't know about you all, but I"m always looking for a magnet to hold things up on my fridge.
