ProjectPuppet.com (I last blogged about them in July) is back with yet another professional-looking puppet pattern; they call this one their "Ovale" pattern. Like all of their patterns it costs $50 and includes the pattern, instructions and a 16" X 36" piece of reticulated or "Scott" foam (contrary to what they claim, you certainly can find reticulated foam in lots of stores) which is presumably enough to build at least one puppet.
