Dh thinks we should get her one of those children's sewing machine that everyone loves to hate, and take the needle out. That way it will make all the noises and be completely safe. Then later put the needle back in when she's ready to really sew.
I'd get her one of those Janomes if they weren't $100, anyone have a child's sewing machine they'd like to be rid of? I'd be more than willing to take a working vintage. ;)
