I busted about 8 skeins free from my stash by taking a humungo bag of lamb's pride superwash to my daughter's Girl Scout troop and getting them started on knitting a Beanie Baby blanket (you know, a swatch ROFL). They each picked a skein of yarn that they liked (I had a rainbow of colors in the bag), and I taught them to cast on and then knit every row. I quickly showed them how to cast-off too, although that may need a refresher lesson once their blankies are done.
It was really cool to watch them figure out how to knit - with their different personalities shining through. Some knit loosey-goosey, some more controlled and tight; All figured it out.
My daughter has picked up her knitting since then a few times - I tried to teach her about 2 years ago, but it frustrated her.
At a previous meeting, they had made their knitting needles - by sharpening and sanding sticks (recycled from chicken-on-a-stick from Friendly's I believe ROFL), and making Fimo-clay characters for the end.
Gotta love the enabling process - and my stash is a little lighter to boot!
