FADING ISSUE: We've tried a product (uv spray) to help thwart quick fading and it seems to help extend the life of the knit graff. Other than that we reverse the knitting and reuse it if we can.
It doesn't get smelly as some might imagine, or get infested with bugs.

Yarn Bombing Book: I finally got a copy and wow! Okay, yes, I am chuffed as punch they used so many of my photographs for the jafagirls work. But that aside if one isn't into crochet/knitting it would make a great coffee table book. Visually the presentation is fabulous and the range of work really showcases the breadth of creativity. It gives a good idea of what yarn bombing is about, the different types around the world, patterns, interviews, and basically is a cultural reference to a movement that seems to have captured the worlds imagination and taken knitting/crochet to a new level of expression.
