I volunteered for the Martian Marathon; an event that I've volunteered and ran in the last 2 years. Well, this year because of my recent knee surgery I can only volunteer. Yes, I'm bummed.
I just have to dress up for this event! This year I added a knit wig in a silvery white to go with my costume. This is a Halloween costume that I made a few years back and of course you can't wear the same thing every year for Halloween but you can for the Martian Marathon! The pattern for the wig can be found at Knitty. There's more about the wig on my Ravelry site.
