I have two wands. One is made out of an oak branch that I aquired in Northern California in the middle of the woods. I put a quartz crystal on the top and tied it down with some hemp (I make hemp jewelry, so I have tons of hemp around).
The other one I have is one that I am not sure what tree it came off of. It was given to me and my husband as a wedding gift from a friend of a friend (his name was Leonard). The wand came from Leonard's magickal garden. Right now there is nothing on it, its just a skinny branch, but someday I will put some ribbons on it.
Here's a picture of my altar (Its not a very good shot, its kinda dark, so I hope you can see it):

The wands are right there in the front of the altar. The dark one is the oak wand and the skinny light one is the wand from Leonard.
