There are certain essential pieces of equipment you need when you’re a knitter. You need yarn, obviously. And you need knitting needles. (The longer you’re a knitter, the more amazing your array of needles). You’ll also need a few notions like stitch markers, tapestry needles, perhaps a stitch holder or a cable needle. All these things, though they add up, don’t cost much individually.
For me, there was a bigger-ticket item I wanted, one that felt decadent because it was so much a matter of convenience, not necessity.
