Too young? Heck, no! Obviously, there's no age requirement to post to this site, so as long as you enjoy posting here and find value in doing so, then by all means post away.
I've found that this site is for everyone--females, males, young people, old people, young at heart people, people who never want to grow up, etc, etc.
Our common bond is knitting, and that trumps everything else.
So please keep posting. I enjoy reading your comments/questions, and I'm always thrilled to see everyone's new knitted and crocheted creations!
