I am the youngest of 4. The next sister up sewed magnificently until shortly after her marriage, then nothing. The eldest did some crafts in HS and college, then went on the med school and became a neurosurgeon, so had no more time for crafts. My mother knew how to hem and do French knots, period. Both my grandmothers, and my great grands were very creative needlewomen, amoung other skills. My Dad did everything from making shoes and various musical instruments, to weaving, spinning and tailoring. I am the only one to continue to be 'crafty' in adulthood. My maternal grandmother designed and built her own house. I think I got my crafty genes from both sides. Like my grandmother and my Dad, I have done some of a huge number of crafts.
