I like your way of thinking! Welcome back to knitting.
What you need:
after you get the material, make a test piece (that you can rip out afterwards, if you want).
what way did you knit before? Yarn held on your left hand (Continetal style), or on your right (English style or throwing)? Do you want to stick with it? then do.
The videos here are mostly given in 2 options so make you life easy and take the right videos.
practice a cast on (for example long tail or cable).
practice the knit stitch and the purl stitch.
practice a cast off.
then you are good to go.
dish cloth are a great way to start, they are small, quick and useful. They do not have to fit you, they can be outrageously colorful or really plain. Freedom, I guess!
Every project will demand something else anyways. A nice combination of stitches, increases and decreases... that will come with time. Once you know something you can just keep practicing until you are perfect, or chose a next pattern to push the boundries.
so when you chose a pattern, read it through carefully and try to understand all terms. For most things you can look up the videos here.
If you get stuck, just ask here. We are many, we are quick and there is a lot of knowledge here
Since you want to knit, we will get your needles clicking.
