I give all the credit in the world to the lovely CJM for finding my new favorite website, Paperless Post.
Paperless Post allows users to create custom online invitations and announcements. New members automatically receive 25 stamps. Users can choose between classic and modern and a number of backgrounds, fonts, and motifs. Additional stamps can be purchased in bundles and never expire. This is one of the most creative, fun, and user-friendly sites that I have come across in a long time. Combined with my recently redone studio apartment, I cant wait to host fabulous soirees this summer.
P.S. We all know that I'm snail mail's biggest purveyor, but now that postage just went up to $.44, this is a fun way to save both money and paper.
