God, I want one of those. I'm not usually big on overtly "girly" things (though I'm certainly not what you'd call a he-man by a long shot), but I think those are so cool looking. I know I'd never leave the house with it, but I'd love to have one to hold my knitting stuff. The more garish the colors, the more I like those bags (NOT that your colors are garish--I mean I them in even wilder colors). I bet it's fun to knit with bright colors. I tend to lean toward the more somber end of the color spectrum so much of the time.
I've never felted anything, and never really got the point until youse guys started posting pictures of your booga bags. Now I'm working up the courage to try it.
