Knitting

I put together a Ravelry search for you to start from. Knit, difficulty level 1, website patterns, cowls - looks like you have to be logged in to see the search page.

The thing to search for (in addition to gaiter) is a cowl. They're a tube-thing that works like a scarf. Some are smaller tubes that fit like a gaiter (if I'm thinking of the right thing), and some are scarves with the ends stitched together - you can decide if you want to make in the round or long, using some fancy stitches or doing nothing but stockinette stitch.

Some of the websites will have written step-by-step instructions that work for you, some will be a little confusing, and some will only have videos. It's going to be harder for me to pick anyone specifically, because what I find useful might not be as helpful to you.

Don't be afraid to start over, either. If you're not happy with the pattern, find something else that you want to try with that yarn and start again. You will probably be happier in the long run if you don't force it - and you get to practice the cast-on! (Seriously, long-tail is a really useful cast-on to know!)

Hope that some of this was useful for you! Good luck!
