I did much the same as many above with granddaughter. She was about 7 with her first venture where she picked out fabric and I cut it, and she sat on my lap. This year, she is 9 1/2 and I showed her how to use the machine, what 1/4 inch seem looked like and set a guide and she did it mostly herself. Of course her seams were wonky and sometimes she forgot to put the presser foot down, but she was mighty pleased with herself. I glue basted it for her and she quilted it, next to the ditch. I put the binding on and she sat with me while we sewed it on the other side. I let her make her own mistakes and didn't want to discourage her with looking for "perfect". "Good enough" was good enough for us. I kept telling her she would get better with practice and there are no "quilt police", and just to have fun. She doesn't live near me so our efforts are few and far between.
