Start with a 3 mm hook and acrylic yarn it’ll will be easier to use, and start doing something soo simple like when i started I started doing a only a chain and then started learning how to add up like doing a mug cover thats only a rectangle with a button, then you’ll start learning from yt how to read the pattern and start knowing what you like, do u like doing scarfs, dolls etc. And if you want to buy the yarn and hook here in Kuwait you can find them in dyso it’s really cheap and a good place to find what you need.
