How should I deal with this?

I make fake id's and drunkenly told this really nice girl I'd make some more, I only had mine before and I don't mind getting people drink but she's broadcast my number on bbm saying I'll make them, of course I don't want that much attention drawn to it and cba to make that many, I've got loads of texts saying 'cn u make me fake id plz bub' how can I tell them no? Thanks :S
