Of all the needlecrafts I have tried I've found this one to be the easiest. It has two stitches unlike the dozen or so for embroidery and uses two pin-like devices instead of a single shallow hook like crochet
However that being said you do need to get used to a different handhold on the needles and you have to be able to count. You have probably heard this line a time or two: "Knit 1 Pearl 1 repeat 10 times" or something similar.
The two stitches called knit and pearl is how you make a row. Any project you make requires a lot of rows and often the stitches change order & number in each row for several rows then you go back to the first row and repeat until your item is finished. As I said a lot of counting because if you get a row wrong or forget a stitch your whole project gets messed up and you have to tear out your stitches until you get back to the place you made the mistake. After which you have to redo the stitches you pulled out.
I have found that if I do the project in all knit or knit one row, pearl the next it is very calming. It's only when I try fancy knit patterns that I need to really pay attention to what I'm doing because the counting is essential to get the pattern right. With knit one row pearl the next if you make a mistake you get an interesting raised or indented design on the item.
To start knitting you make a slip knot on one of the needles. Once you have the slip knot you are ready to cast on. Really remembering how to make a slipknot was my biggest issue when I started. Below is a video I found on YouTube that shows how to cast on
This is only one of the many Knitting for Beginners videos on Youtube. Click the link to find dozens more. If you need an active meditation method try knitting it works great.
There are few yarn shops left but if you can find one or you know someone who knows how to knit they are usually more than willing to teach you the basics and help you out.
