I created my own Wedding Invitation, and I love it, so I thought I’ll share.
It was printed on 270 gsm Coronado Warm White stock, Double Sided because of the de-bossing (the opposite of embossing).
For the envelope it was printed on textured local (Indonesian) paper. I forgot the name but you can see the texture on the first picture. Most Indonesian local paper are not very nice, but I think this particular paper works well for envelopes because it is not too thin, and not too thick either. Also the texture gives the envelope nice look.
