I was just thinking of teaching my four year old niece to sew. I saw two different sets of the old time sewing cards that you use a big needle and yarn. They have nursery rhyme pictures on them with big holes. (Anyone remember these?) I am getting them for her for valentines day.
I taught my friend's granddaughter when she was in first grade and she still sews to this day. She even has taught her step sisters.
I taught my friend dara to piece quilts and to crochet some fifteen years ago. She still does it when she has time. She is in studying to be a doctor now.
I even taught my sons these things too. Although only one of them even stayed into art. They still know how to sew on thier buttons by themselves, or repair a tear.
