I found this on Etsy today. I want to make one, but I have no use for it. So here's the deal: if you buy it and have it emailed to me, I'll make it for you within a week of receiving it!
We both win! I get to make it, plus I have the pattern for future use, and you get a knitted power cord in the mail! Pretty sweet, huh?
(Maybe I could use it as garland on my wack-o Christmas tree this year?)
