Er, that's about it really.
I have seen lovely sweater patterns in this style for knitting but not crochet. I know how to knit, but my arthritis finds it easier to crochet, so if anyone could forward a pattern to me or give me a reference so I can order it I would be very grateful.
DS is 18 months old, so anything in age 3 upwards would be wonderful, not that I'm slow, but he has lots of jumpers to see him through until then
