We got a direct message earlier today from Twitter friend @KnitoriousMEG telling us about her most recent yarn bomb. For those of you not familiar with the yarn bomb (we only recently learned about them), it's the practice of knitting pieces for public spaces. You could call it graffiti knitting, but we like to think of it as graffiti with a little more class. Well, KnitoriousMEG has been yarn bombing Richmond, Virginia, for a little over a year now. She says her favorite things to tag are "something that once served a purpose but now doesn’t, like a signpost with no sign." The target of her April yarn bomb does in fact serve a historical purpose, but we think you'll agree it looks much better with some embellishment. Richmond's Monument Avenue cannon, situated between Robert E. Lee and Jefferson Davis, now sports a cozy, colorful cover in honor of the 150th anniversary of the Civil War. To see more photos and find out what KnitoriousMEG bombs next, visit her blog, like her on Facebook or follow her on Twitter.
