Knitting Needles etc.

I’ve started knitting and have been practicing with cheap yarn that I bought at a craft store. I want to start making headbands and obviously want to use better yarn, but I am not sure what the best would be. Anyone have any preferences or recommendations as to what kind of yarn or any specific brand of yarn? Thanks in advance!
I’ll be using a US 7 needle and a worsted yarn

I think the Hengyuanxiang’s better. I have many friends like this brand of yarn.

this question is pretty self explanatory.

stick pins or quilting pins… same thing, different length.

ETA… dress maker pins DO NOT have balls on top.

Is there a full range? Try this link, it may help.
