I think what you did to make their theme part of the quilt was wonderful. I like what you did. I think it was rude of those people to behave as they did but they probably don't even realize that they reacted like that. Sometimes people get tunnel vision when they are in wedding or baby show mode and forget their manners.
I'm waiting to see what my sons girlfriend is going to do when I give her one of the baby quilts I made is jungle theme. It has monkeys and that is the one thing she says she didn't want. I found that out after I had made it.
