I have painted some - but I did not put the lights in.

I am not a very good painter, but I love to try :)

I found that it worked best to give the blocks a light coat of clear spray paint. The paint went on so much better over that, than just the plain glass. When I was finished, I give it a couple more light coats of clear to seal it.

On the gallery side on the Painting forum, Anjabee just painted a cute glass block. You might want to take a look and ask her questions. She has also done them other ways as well. Luvs

I did one you can also find it on my Blog ½ way down
