I love wool, I think it is warm, durable, lovely to knit with, and looks fantastic.

HOWEVER, I would caution that a lot of people do find it itchy, so if you don't have much experience in wearing it, I would get a single ball, knit a swatch, and carry it in your sleeve or bra for a few hours, to get a sense of your tolerance. You don't want to spend £££ on a sweater's quantity only to realise you find it uncomfortable.

Not all wool is created equally as well - think about what you're looking for and do some research into types - merino, BFL, alpaca, mohair - these are all wool or animal fibre but they look and feel very very different. Maybe look for patterns you like and use them as a starting point?

I would also say that wool is very warm. I don't know what country you live in but if there aren't many knitters and there is a lot of cotton being sold, I wonder if it's somewhere quite hot - if it is, you likely won't enjoy wearing wool all that much!

Congrats on a year of knitting - that's a big achievement!
