If you're thinking of getting your work into an art shows, CaFE is a great website to find one that might fit. It's free for artists and allows you to look through an extensive database for calls for entries all over the country. I usually sort by state because I like to find shows that won't require me to ship my work too far.
It helps you keep track of which shows you've entered and which pieces were accepted or rejected.
When you submit for a call you upload your images to an online portfolio which, you can then access for future calls. Having my images already prepared and ready to go for future calls is so helpful.
You usually have to pay an entry fee to apply for the call, but CaFE is completely free for artists. Using this to find calls for entry opened doors wide open for me and I was introduced to opportunities I never would have known about. It's a great way to start getting your work into more shows.
