Envelope stamps

I’ve just finished some line art that I’m going to carve into stamps. After the stamps are carved, I’ll be able to decorate the envelopes for my card sets. I’m through with using store-bought stamps for my designs.
UPDATE: Here they are carved and stamped on paper. I like how the stamp material comes through the design with rough artifacts. They also look good on colored paper. I got the carving blocks from MisterArt.
