I grew up in a crafty family, so I've been crafty since before I can remember.
When visiting my dad's parents, I remember playing with some blocks my grandmother had for planning out quilts, and when visiting my mom's parents, I remember being fascinated with my grandmother's knitting. We had various crafty things to do at home, like the Woodles - they were small-ish, flat wooden shapes that you could paint and glue together, and make magnets and things. Play-doh was banned in our house, though (we had carpets).
In grade 5 we did a unit on transportation and one piece of homework was to make a vehicle out of things found at home, and while my classmates all brought in tissue-box cars and things, I had an airplane made out of a spark plug, a tongue depressor, a Popsicle stick, and some Lego wheels. (Dad helped with the materials acquisition!)
Mom liked to make things with plastic canvas, then later really wanted to learn cross stitching, but wasn't sure how to go about it. When I was 11 I went to a summer camp and learned some basics of cross stitch, and came home and taught mom. (And boy, did she ever run with it!)
