We had a Halloween party Saturday night. Becca and I worked together on the decorations; I liked the way they turned out.

The ghost luminarias are made from milk jugs (I'm sure you totally couldn't tell). I used flameless tealights inside. I thought the tealights worked great, but if you buy them, be advised that there will be a lot of duds in every package. The first package had about 50% duds; subsequent packages had maybe 25% duds.
