Glass Block project

I have been wanting to try this project for some time now. The reason I had not done so until today...is that the blocks have to have a hole drilled into the side...with a diamond drill bit and hopefully not crack the glass. But, today I was at Lowe's and saw these in the Christmas section and they already have a hole drilled plus a plug. Bingo! DD was with me and said she would love to have one done up as a present for under her tree at her apt. Sooooo, I bought a block, picked up some spray frost paint and some ribbon and a strand of LED white Christmas lights...the LED since they stay cool.
At home, I sprayed the frost, let it dry and then stuffed the lights inside and put the stopper in. Then I used the ribbon around the outer edge and made a bow. In real life, this looks awesome with the lights in a dark room.
I plan to make another one and use battery lights so I can set it on a table with out being plugged in. I will either paint a scene or print something onto velum and attach it to the sides of the glass block and hope the lights show through.
