Hey there, we're happy to hear your interest in participating! There are many ways to make a portfolio and they will differ depending on your art form. Many people use a Google Drive folder since it is easy to organize and label.

For writers, an AO3 (archive of our own) account can also serve as a portfolio. In some cases an Instagram can also be a portfolio if it is primarily used for your chosen art form (art, merch, or cosplay). Wix also has a free option to make a website with a portfolio. Any of these options are fine!
