Russian Nesting Dolls - called "Matryoshka" - came up on the list.... Here
is site that goes into the history of the dolls.... LOTS of images.

This site has many examples of Russian crafts
http://russian-crafts.com/index.html
... good images. I recommend it for anyone doing a unit on Russian crafts.
Not necessarily a site you would have kids explore (It is a commercial
site) - but for you to grab images for PowerPoint presentations. Fair use
allows you to use them for in class only. Check Traditions and Folks Tales
too. Losts of stories to read to the kiddies.
