My first exposure to knitting was watching my grandmother's fingers flying away making a jumper and having been amazed at what I saw, was doubly amazed when I saw my mother doing something similar later that same winter! I was probably about 6yrs old and asked to be taught. Hours of patient instruction later, as winter turned to spring, I apparently announced that i didn't want to knit - it was much more fun playing outside, climbing trees, going to the beach.
Years later I am at university and suddenly acquire a "knitting-bug" and make myself an extraordinarily multi-coloured long cardigan. Looking back I am impressed.. it really was intricate. Not sure what happened to it. Fortunately the "bug" lasted long enough for me to finish the job and vanishes again.
Even more years later I inflict a couple of jumpers on my, then toddler, godson - Aran style - and again just manage to get the projects completed before total disinterest kicks in!
