Crikey those paintings are incredible!
My better half recently took part in a ladies' "Retreat" day at the local church that hosts the playgroup our daughter goes to every week. She taught people to crochet, showed off the sorts of things you can make, etc, and by all accounts it went down pretty well!
Making up the packs for each of them was a bit of a faff (one crochet hook, half a ball of wool wound off, a little printed guide), but worth it as the feedback has been very positive.
