At least five years ago, my daughter LadyU asked me to make her a balaclava she could wear while walking the dogs during winter. It took me a long while to finally get around to making it for her, but hopefully she will like it! (There has been a bit of a long saga predating today's project.)
Inspired by the Alpine Ninja balaclava, I used the Crochet with GG video tutorial at this link to learn how to make the alpine stitch in the round (top down), but I worked the top of this hat differently than was shown in the video.
Top part of hat (above the opening for the wearer's face) is worked with a J/6mm hook; bottom part of hat (cowl) is worked with a K/6.5mm hook.
I prefer to work hats top-down, but I don't like patterns where the top stitch count increases so rapidly that the top of the hat curls ferociously until you work far enough down the sides that it helps to tame the curling a bit. That was what was happening on this one when I tried to follow the stitch counts in the video tutorial. So instead I started with 10 sts and made standard increases on that count (next row 20, next row 30, etc.).
My goal was to end up with a total of 72 sts after all the increases, but somehow I ended up with 76 sts on the last increase row; I figured that was close enough (the most important thing was to end up with an even number of sts for the alpine stitch to work). The crown is worked with alternating FPDC and BPDC sts because it's easier to do increases with that combo of sts than it is to try to do increases in the alpine stitch, and I like how the alternating FPDC/BPDC more closely resembles the texture of the alpine stitch at the crown (it looks better than making the crown with all plain DC).
I didn't actually keep count while working the crown, but I think the crown here is 22 rows in purple (the first 6 or 7 rows are alternating FPDC/BPDC increases, then I switched to alpine stitch). If you want to change colors where the balaclava splits to make the face opening, it's important to end the first color on an alpine stitch row where you're working the FPDC/DC sts. The next row is a SC row. I was beginning/ending rounds at the center back. Place stitch markers at each side of the face opening. Then on the SC row, join your new color and SC to first marker; FSC for however many sts you need to skip to reach the next marker; at the next marker, SC normally to the end of the round. This way when you continue the following row in alpine stitch (FPDC/DC), the color change will look better because the post stitches are reaching across an SC row of the same color (rather than an SC row of a different color).
That's just the way I wanted the color change on this hat to look. It probably could look cool to do the color change over a contrasting SC row as well (so if that's the way you want to do it on your project, go for it!). I also increased the stitch count for the cowl portion to 78 for a bit more ease around the wearer's face.
It only took a few days to complete the crocheted portion of this project. The part that subsequently took months to do was searching for an acceptable pair of buttons to sew onto the folded tab as the last finishing touch. Originally I wanted to use a pair of Pokemon character buttons, but I wasn't able to find any I liked or that would be suitable here. So finally I settled on these washable coconut wood buttons, which I think look nice with the project.
Updated to add a removable 3.5-inch pom:
