I hope this post is okay here?

Basically I can knit, and I can purl. I can knit a long 'thing,' and once, using circular needles, I made a 'tube' but I'd like to do more

Can anyone recommend a resource, preferably written with pictures, and maybe a link to a video to progress to something more complex? (it would help if the video is simple and slow)

I would like to eventually make a sock (I must be a masochist).

The thing is I struggle to understand the 'code' of patterns so I need something really basic, I'm also autistic (I don't know if that would cause issues, per-say, but thought I'd include it in order to give an overview of potential difficulties)

Thank you for any help you can offer 👍
