Vendors are busy and its not unreasonable to think they may actually take weekends off. I would not take it personal that she was not able to respond, instead take it as though she may not be able to handle your rigid timeline. I respect the talent of the vendors I've previewed here very much and am amazed at what I see. Even if it took a while longer, I realize I am not capable of doing what they do and therefore must wait if I really want their products. There are a ton of brides beating their door down daily! I'm sure you will find someone to help out. And perhaps you can mail your mom the samples for her viewing as well. Good luck!
