Knitting has a lot to do with muscle memory.
It can be hard in the beginning, learning to hold your hands a certain way and make the right movements.
And, depending on what you’re trying to knit, the recipes can be confusing.
Nobody is good at something like that the first times they try it. You just gotta keep trying and eventually you’ll see improvement
Knitting might just not be your thing. Everyone is not good at some things and good at others. Some people are better at reading, some at math, etc. This is the same as that. Don’t be so hard on yourself.
Knitting is very repetitious and counting. Doing the same thing over and over is hard but fulfilling when you are done. I’m sure you can get it ! Takes practice. My MOM liked it too and we have some stuff of hers still, blankets and scarves. Maybe start small or do a patch work in pieces- one piece at a time?
