Thanks for all of the responses! My internet connection has been down for days so I am only just seeing them now.
I have a customer who sent me these photos (and a ton more) to give me a sense of what she likes before I designed a quilt for her. I have no intention of using any of these patterns as they stand - but I wanted to know the names in case I ended up using a block as part of my quilt for her, because I am terrified of the whole copyright infringement issue. (As it turns out I won't be using any of the blocks.)
Ghostrider, your knowledge of quilt sites and sources is truly awesome, and thank you for the idea of saving the site name in the download name. I usually just bookmark whatever site I like, but I will pass your suggestion on to any future clients who will be prowling the web for ideas!
Thanks again for everyone's help.
Alison
