First of all, I'd like to thank everyone for their kind words and encouragement...it really helped lessen the blow.
Things have been worked out between the other person and myself. They aquired the pattern from someone at a gathering and had no idea mine even existed. One look for herself though, and she was pretty sure that her gathering friend copied the pattern from me.
She has since removed offending items, and was very kind and accomidating about the whole situation. I'm glad that it worked out.
I don't know exactly what I can do to protect myself in the future...you want a photo to represent detail, and I can't zoom in too close and detailed without giving away the pattern, essentially.
