Here's a couple for ya:
Building a NURBS Hand by Jeremy Birn:

Quoting from the first paragraph: "This tutorial was written with specific command references and screenshots from Rhino 3D, but the same steps can be followed in other NURBS modeling packages..."
Also, right here on Highend3D, there is a three part character modeling tutorial by Michael Bazhutkin. Part 2, called: Head, hands, cloth (seamless modeling in Maya) can b found at:
http://www.highend3d.com/maya/tutorials/mi...lb/seamless2.3d
While it turns out to be a little short on hand modeling details, it has this excelent screen shot:

Good Luck...
