Swapping is a critical part of the Artist Trading Cards movement and has been the catalyst for its exponential growth.
If you are just starting out and interested in finding opportunities to trade ATCs, the internet is a great place to start.
Internet searching is not only a good way to discover in-person swaps happening in your area, but there are also a lot of online resources available that were created specifically for the ATC community, helping new artists get started and avid ATC artists to increase connections and get exposure for their work.
