>>I chose three of the public cards, though I'm not sure how many fills I'll actually get done. <<

I wish you luck with it.

>>I'm thinking I might play the solo card by actually doing the prompts instead of writing about them, but I'll have to double check the card to be sure.<<

:D You should totally do that!

>> Or I could always do some of both.<<

Fills can be anything you want. Mine are usually poems, but occasionally fiction, and I've done a few with crafts or photos. Mix and match all you want. The only time the fill type matters is for certain achievements or if the fest host sets that as a parameter. As far as I'm concerned, people could screw their way through the kink category and call bingo.
