We have all these people that we usually give gifts to but we just bought a house and we are a bit broke. My uncle gave me this idea and it was really easy to do and not too expensive (about $10.00 Cdn each)
Go to Home Depot (or similar store) and buy the largest glass drill bit they have (a half and inch and about $15.00)
Go to a store that has glass blocks (mine was a local masonry store and they were $7.00 each)
Go to a store that sells wide wire ribbon (or use some you have)
Buy a small string of white lights on a white cord that only has one plug (they are about $2.00 each)
Take stuff home
Place glass block in cold water (used a laundry tub), slowly drill a hole in the back of block to one side with the drill (and drill bit) lubricate with water so it doesn't get hot
Let block dry
Shove Christmas lights in hole letting plug dangle out
Tie on a ribbon
Voila you are done.
We didn't even break one block and we made 4 in about an hour. It was fun being crafty with my boyfriend too.
