Is it practical? Maybe not for a North Dakota winter (we'll wear ours in spring), but it's a totally geeky accessory that tells everyone you've got the power! Last we checked you can buy yourself a knitted power cord in charcoal, orange, and yellow - and if you're crafty enough to pull it off, you can buy the pattern and make one yourself in which ever color you want! Stay plugged in to your fashionable geek side! Found at KnitKnit's shop on Etsy.com.
