I'm late getting on this topic, getting caught up on the shows! I've had a series of quilts in my head for YEARS but I thought I'd probably do photo-mosaics, and now I'm re-thinking that! now, what did I do with those photos???
Also, re: the newspaper photos, I doubt this is the case for Mandy (unless the photographer SOLD the pic to the paper, which I highly doubt) but if a photo is shot by a staff photographer or a paid "stringer" photographer, then the publication owns the copyright, not the photographer him/herself. Sometimes even the photographer doesn't fully realize that, so they might actually give you permission that's not theirs to give...
