Thanks so much guys! I'm really surprised Nick isn't keen on the third. Originally he liked them but since finding the first ones he's been put off. Jo I definitely know what you mean - I am really conscious that while I want an art deco themed wedding I don't want it to look like a fancy dress party, and a lot of the stationery sets look a little... tacky?
I think I am going to order samples of 1, 2 and 3 and see how they are in the flesh. The envelopes on the first are beautiful and I think that is what we love about them though the sharp, geometric lines of the third make them more true to art deco in that respect I think.
