Hi, Meli and welcome! :waving:
You've definitely come to the right place to begin your knitting adventures! The videos available here are awesome and will cover anything you need to learn getting started -- and beyond!
When I first got back into knitting I made scarves - LOTS of scarves. My family and friends were in heaven and stayed nice and toasty warm all winter!
I used Lion Brand Homespun yarn and big plastic #15 needles. I pulled one strand from the center pull and one that unwound from the outside of the skein and knitted using a double thread.
I cast on 12 stitches and just did knit stitches for every row (called garter stitch) until the whole skein was used up. I bound off and had a wonderful, warm wooly scarf in my hands. It was magical!!!
It was a great project for me to ease back into knitting which I hadn't done for many years. Now I'm hooked!!!
I would recommend that whatever pattern you start with, make something that really appeals to you and that you have a need for.
That said, I'd also recommend that you collect needles as you go from project to project for awhile, trying out different materials to see which you like.
When you're ready for it, check out the KnitPicks Options interchangeable set and/or their Harmony Wood. They are WONDERFUL, in my opinion, and I'd be lost without them. Other needles I've tried haven't measured up to the Options.
You'll probably start off with metal long straights which is a good place to start as you become more practiced.
And don't forget - any questions or problems you run into can and will be treated kindly and knowledgeably by the wonderful knitters on this site.
So, happy knitting and make sure to let us know how it's going!
