I had my sister design the 5 x 7 in. invites in adobe illustrator and we had them printed on a pearlescent white/ivory card stock. We also had mini prints printed from printstagr.am to include in the invite. Finally we bought a bunch of fun scrapbooking paper from Hobby Lobby and borrow a cricut to cut out a bunch of customized "confetti". This gave guest a little extra surprise when they opened the invitation!
We ordered taupe brown recycled paper envelopes from paperandmore.com. The labels we printed ourselves on the transparent labels you can buy from any major office or department store. To jazz them up a bit we utilized the same wood grain background.
Finally, the envelopes were sealed with a picture sticker, which we also ordered from printstagr.am.
