$1 Budget: Dollar Tree Lights!
Lights can come from all kinds of stores, but I've been really impressed what I've found at the local Dollar Tree. Sure, it's all cheaply made, but I can afford it and there are some really interesting applications this time around. Some of these ideas aren't fully formed yet, but I like sharing anyway in case something strikes a chord. Look for slightly more money being spent (as you have been encouraging me to do so) in the near future.
