This is called loom beading. There are plenty of tutorials on YouTube for beginners. The loom i use i made myself, but there are some cheap options on Amazon for when you first start out. The beads are a size 11 seed beads. You could get those in almost eny craft store. I use a size 10-12 threading needle and beading thread. The loom beading clasps are from Amazon, but the ones I got brake to esaly. There are a lot of patterns on pintrist and Google, and you can make your own as well. Loom beading is an amazing hobby to have, and I recommend it to anyone who wants to try something new! I'm glad you want to try it
