Long requested crochet tutorial is finally up!
If you want a printed pattern, I’d suggest Sarah Arnold’s Divine Hat however, there are no instructions for the 2-color version. Be aware that there are MANY versions of this design out there under various names like “crochet spiral beanie” or “easy seashell hat” and more. I have no idea who to give original credit to so I’m recommending Sarah’s pattern because that’s the one I used.
In the video, I reference 2 files that can be found here: my usual Hat Sizing Charts and one where I made Candy Swirl Hat Notes suggesting yarn and hook sizes. (Please remember these are only suggestions to help you find a starting point for sizing this difficult-to-size hat!)

I watched your video on fixing holes in garter stitch. Helped alot. Thanks.
Would love to know what yarn and color your item is. Love the fall color.
Thanks

Oh, goodness, Pat! That video was from 2015 and all I can remember was that it was a Paton’s Sock Yarn! I bet you can search that much and see what colors they have now. If that particular one has been discontinued, there may be a similar one.
Hello from Michigan, I’m a new crocheter could you please explain the difference between those thinner yarns.
Thank you
Hmmm…. I’m not quite understanding your question. Are you asking about yarn weight? If so here’s the Craft Yarn Council’s standards: https://www.craftyarncouncil.com/standards/yarn-weight-system
Hi, your video was really helpful, especially the bit about how to not get the yarns twisted. I’ve made quite a few of these hats, both two-tone and the standard one colour, and wonder if you can answer a question for me. I found they tend to come out a bit too pointy, especially the smaller sizes, so I tried omitting round 2 (dc around all posts) to see if the faster increase would round out the top. It did indeed produce a rounder topped hat. I haven’t tried it with the two-tone hat yet. Do you think the round 2 actually serves a purpose? Why not just go straight to doubling? Maybe I’m overlooking something.
I don’t know since mine aren’t pointy! I suspect it has something to do with the difference in our gauge. I personally like the look of the solid “center” that round 2 creates but as I preach all the time… “There are no rules in crochet!” Adjust the pattern to suit your own gauge/likes/dislikes!
