I want to knit a cardigan sweater for my great granddaughter. She is a size 3T. I don’t see any instructions for that size. I am knitting it in worsted weight yarn.
Hi and welcome to KH! Do you care to give us the pattern name or if a link is available? That way we can help you a bit more.
Children’s patterns usually go by chest size. Here’s a chart with measurements that may help you figure which size to knit. It doesn’t have a 3T, but if you do a size 4 that should work unless she’s really small for her age. I’m making a sweater for my year old GD about a size 2-3, she’s very tall and fairly big.
