Good for you, teaching your grandson how to sew. I taught my son too. Now he's 6'8 and 32 yrs. old. He recently bought his own sewing machine so that he could mend his own welding clothes, which is great since I don't have to do it anymore! Last week he had to mend his wife's blouse, because she does'nt know how to sew. You can be proud of your grandson!
