I stumbled upon a stationery company called smock this morning. So lovely. All of the stationery is letterpressed, which I absolutely love, and very reasonably priced especially considering how "eco friendly" it is:
sustainably letterpressed on bamboo paper
packaged in a clear sleeve that is petroleum-free, tree-free, and certified biodegradable by the Biodegradable Products Institute
They have several gorgeous wedding suites, a variety of wrapping papers and fill-in invitations, as well as a very nice assortment of artsy-yet-classic correspondence and greeting cards.
