craftgrrl | copyright and painting on knitting

okay, i have a question that's really bugging me. i've looked at past post re: copyright and am more confused than when i started! if i wanted to screen print song lyrics or images of people for my own use (i.e. one or two shirts), it's a violation of copyright, correct? now, if i were to credit where the words/images came from, would it still be a copyright violation (as in if you quote without a citation in a paper it's plagerism)? i won't be using these things to damage the creator in anyway, though i'm pretty sure it doesn't matter how i'm using it. i just want to proudly display my love for the music i listen to without stepping on anyone's toes. it's not like i'm reproducing shirts already made and being sold commercially either.

and i was wondering if anyone has had luck painting on knitting. i knit a wristwarmer cuff sorta thing today and wanted to paint a design on it (i was thinkin of a band logo which goes back to the copyright deal). it's knit really tightly, but i'm worried the design will crack apart (or off) when i stretch it over my hand.

Thanks for all your help! i *heart* you all. :)
