Upper-right corner has a stamped stamp! I carved this with PoStUdIo at the bottom and 3d at the top. It has been stamped in black ink and colored with watercolor markers. I added a travel sticker in the lower left and the greeting in the upper left. The flowers in the greeting matched some others on the sticker sheet so I placed these as a bottom border.
I pulled the colors from these elements to color in the stamp. A fine-line pen was used to add borders and the address lines.
Since this is a card rather than a real postcard, the address is left blank and any further greetings will be placed on the inside.
