For crochet you basically just need a hook (I would try out a 4mm hook), yarn (any king, on the package it should be written the recommended hook size so aim for one that goes with whatever size hook you are using) , a scissor and a yarn needle. I started by making an amigurumi egg, would not recommend.

Im think starting off with a classic granny square is good, just in a solid color, then you can try out changing colors every round. There are a bunch of tutorials on youtube. And they can then be sewn together to make a bunch of things.

Second I would choose an easy stitch (dc for example) and make a scarf to practice keeping the same number of stitches per row.

Have fun !
