What are some fun 60's or 70's crafts?

You know what they say -- there's nothing new under the sun! Mosaics were huge in the '60s, especially kits and trivets and such. And weaving those little potholders, you can still purchase the little looms except they're now plastic instead of metal. Also string art, I remember that being big in the '70s -- sailboats and the like. And of course tie-dying. And finally, we used to crack marbles in the oven under a low heat and make jewelry out of them -- have fun!
