My 6 year old just sewed a complete quilt on my Babylock Elizabeth. I did the pressing and cutting, she did all the sewing.

It is super easy because we used the push button stop/start, so she didn't even have to use the pedal. If you are using a pedal-only machine, think about putting some kind of stopper on it so that she can't push the pedal all the way down to high speed. Speed control helps!
