Here's some great recycled paper invitations, programs, save the dates and cards. Several of them are plantable as well. Great quality and you can have them print them or print them yourself.
I ordered the DIY kits for invitations and programs. Be cautious of the size of paper, as not all printed fit the invitation itiself as they are narrow and come precut, and some papers are thicker and not compatible with all printers. I had to use a copy machine to print them. Luckily we had one available.
I would recommend having them print them to avoid issues. But we loved them, and it added to our spring wedding - some of our guests responded and said they already planted them!
