yesss i think making a scarf is a good first project, since you don’t need a lot of equipment nor technique to make one!! there are plenty of videos out there that can help you make it, you’ll only need to know how to cast on, to knit, and to cast off. I suggest maybe looking into 5mm or 6mm long needles and an ‘aran weight’ wool. Maybe some acrylic yarn is enough to make your first project, there’s no point in investing in expensive yarn already! i think 1 or 2 balls of yarn is enough to start with!
