Hello! Well you sparked my interest and I have found the website to purchase bumperstickers as well as t-shirts etc for Knitter Against Bush. It is www.yarnagogo.com and the merchandise is through cafepress.com and it benefits the MoveOn.com group.
Oooh...Gooody! I like this one almost as much as the one I got before the last election "Republicans for Voldemort" (Harry Potter related, not knitting...but there is lots of knitting IN Harry Potter, so a very loose connection to the thread?)
