handmade paper
Daintree ( is a very good place, kind of dumpy shop, but great paper. I got my wedding stationary there, expensive if you get them to print, but if you dont get very thick or rough handmade paper you can easily print your own.
As regards nice typefaces, a quick search through google will bring up loads of font websites, then just browse the various typefaces for the one you want.
Daintree have, ir had two stores, go to the one near O'Sullivans art supply shop. Actually, O'Sullivans may have nice paper too, but Daintree is more arts and craft style. Not too far from the Bleedin Horse at top of Camden St.
