Can I

knit this hat on circulars? I’m new so any advice concerning it is appreciated!

You can knit your work on circular needles without necessarily working in the round – I do it all the time! I haven’t used straight needles for months.

Yep! I don’t use straights all anymore except the occasional DPN.

I really want to knit it in the round. I guess I phrased my question wrong. I want to avoid the back seam.

You can use dpns, a long needle and Magic Loop, or 2 circs and knit in the round.

Thank you all so much! NOW can I felt it? How much bigger would I make it?
