plushies -- what fabric?

[itcouldbelove.livejournal.com]

When making plushie stuffed animals -- for example, I want to make some monsters -- what would you recommend the best material to use would be? I don't want to use felt, because I would like to use something a little softer. I may use felt for like the eyes/nose/mouth/etc, though. What would you recommend for the entire thing? Thank you!
