Yes, "sheets." I have two personas. (The one I use in my profile picture, and one that virtually no one has seen.)
I haven't made the second one yet, but here's the first!
This is Cascade! He is a Dragonfluff (3/4 Felinefluff, which is essentially a cat, and 1/4 Dragonwing, which is essentially a dragon) and come to think of it, he doesn't have a whole lot of interesting things about him (yet). He is an excellent swimmer and while he can't fly due to how small his wings are, he doesn't really mind, as he has a fear of heights and would MUCH rather stay on the ground.
