This is one of my all me favorite DIY's. My Shooting Christmas Star. I used a wire star from Party City $9.99, comes covered with silver tinsel, looks great even when not lit. I used a box of the round LED clear lights on the star. Then 4--100 strand lights attached for the tails. Simple fast and easy. Start to finish, less than $30.00. This would also look stunning on a garage door, or a pitched roof.
For everyone that asks about Luminarias. It is technically a #4 bag, which is bigger than a sandwich bag. We use sand, and Reed Candle Company Cathedral Candles. Unlike a votive, they just burn straight down into the sand. They last 12 hours or more. We are on a luminaria tour where all the homes do them, it is stunning. If you can't find a #4 bag a sandwich bag will work. Yes, do a double fold it makes the bag much more stable. Get a bag of sand from Toys R Us, and you could use the small tealights in them, but they will only burn about 4 to 6 hours.
Give them a try too.
