One more thing I'd like to mention too, that I've found works pretty well from my own experiences: if you have puppets that require drab/dark/neutral color schemes, even low-quality polyster-based fleece works well, because irregardless of the seam construction, they won't be very visible with the dark and dullness of the fabric; my original Squirrely Squirrel puppets were fabricated with charcoal-colored polyester fleece, and you can't really see the seams at all on them, though for the newer puppets, I'm wanting to switch to short, plush-like fur for their bodies.
