Many folks don't realize how much information for sellers is available right on Etsy! The Teams section of the platform has groups located around the US and each has their own forum - many of which have threads of upcoming events. Find an active team with a thread and keep an eye on it. 

Most folks know that you can buy tickets to events using Eventbrite... but they also have a large database of events on their platform where you can discover local events. A large percentage of the events aren't the kind where you can set up and sell your goods, but there's a lot to comb through and its very easy to find events for very specific interests - and you just might find something perfect for you. 

Eventeny is a platform where organizers can easily set up event applications. Once you set up an account, applying to other shows is a breeze.
Once accepted to a show, you will show up in the event's vendor list - and people can easily find information about your business and your shop. Your profile also offers a "shop" option where you can list products to sell.

You can search for upcoming shows and open applications near you - and the types of events is not limited to just anime or comic cons.

Many cities and neighborhoods have dedicated groups where local creators share information about upcoming shows in the area. There are also tons of Vendor/Craft show groups that share event info constantly. Often, you'll find organization post on these pages when they're looking for more vendors to fill up upcoming events. 

Don't see an existing post? You can make your own post and ask for recommendations from like-minded folks about local shows (plus, you'll usually get extra info about if a show is worth your time or not).

The discover tab on Facebook is another great resource where you can search your area for upcoming events. There's even categories to narrow down your search!

Looking for a local event? Head over to your city or county's official website. They generally maintain a large calendar of events happening in your area. Often, you'll find many small events that may not take the time to register with a lot of the places I've listed above. 

People sleep on google - but theres so much information to find with just a little bit of adjustment to your search terms. Search something like "anime conventions near me" or "craft shows in yourstatehere" (WITH quotation marks). Google even has a calendar of upcoming events near you!

I definitely recommend befriending other artists, creators, and vendors. (Especially ones with a similar audience!) Ask what shows they recommend.
