This thread sent me off to rummage around youtube for fun links. Here are some:


Washboard variety in Seattle

and Japan (there are about 20 of these, including a 6-footer)


This looks like a useful lesson (there are more videos of this session)

This guy uses socket wrenches rather than thimbles (useful since they can be had in very specific sizes and lengths)

spoons

various kitchen implements

1958 Russsian skiffle - washboard on the knees

Same technique, currently in Prague (lots of videos of this band, search "Prague Bridge")

David Holt has fun with it

Michael Doucet and Angela Lloyd have fun
