I had not heard of the online marketplace, Fiverr, until recently. At the site, people can offer services (such as drawing, logo creation, writing, editing) or products, called gigs, for $5.00. Some sellers offer additional services for added fees. Fiverr has a section for postcards, so I put up a gig for postcards from Ithaca. Please visit my fiverr page and let me know what you think!
I participated in a Swap-Bot pi day card/postcard swap. I send the top left card, which I purchased on zazzle. I received the rainbow pi and pi-rate cards from my partners in the swap. More about pi day can be found on the pi day site.
I signed up for a Zentangle Postcard Swap on swap-bot. The only design limitation was a leaf somewhere on the postcard. I made the bottom zentangle first, but didn’t like it enough to send, so I created the top one, which I liked much better.
