Two-color brioche hat: a Knittycat's knits tutorial

This video tutorial demonstrates how to knit a two-color brioche hat. For steps on doing the hat decreases, please see that video at    • Two-color brioche hat decreases: a Kn...  . You can also see my one-color brioche hat video (18:00 min onwards) for these decreases at    • One color brioche hat reboot   a Knit...  .

Needles: US size 7 (4.5 mm, for snugger fit) or US size 9 (5.5 mm) 16” circular needles & set of 4 double-pointed needles in same size.
Gauge: With Red Heart “With Love” yarn (100% premium acrylic), one 5-oz skein (170 g, 288 m), knitting 11 stitches in 1-color brioche knit in flat with US size 9 (5.5 mm) needles = 2.5” width (for 1-color brioche stitch pattern and video, click:    • How to knit 1-color brioche stitch: a...  )
Finished hat size: Unstretched: ~16.5 inches round and ~8-9 inches height (hat stretches to ~21 inches to fit an adult)
Abbreviations: BRK=brioche knit; BRP=brioche purl; K=knit; K2tog**=knit 2 stitches together; P=purl; sl=slip the stitch purlwise; sm=slip marker; YF=yarn forward; YO=yarn over.
**In this pattern, a brioche st is considered to be 1 st, so a K2tog means knitting a brioche st and a single st together.

Designate colors as MC (main color) and CC (contrasting color). Using circular needles, cast on 64 st with MC. Place a stitch marker after the last st before joining in the round when doing the first set-up row. At the end of each row, slip the st marker and begin the next row.
Do the following 2 set-up rows (only once):
Set-up row 1 (MC): K1, *YF, then sl1. Repeat from * to the end of the row (after each sl1, keep YF and then do K1 as shown in video)
Set-up row 2 (CC): With yarn in front, *sl1, YO, BRP. Repeat from * to end of row. Then do Rows 1 & 2 as follows:
Row 1 (MC): Take the yarn to the back, then *BRK, YF, sl1. Repeat from * until the end of the row (after last sl1, bring yarn all the way around the stitch as shown in video).
Row 2 (CC): With yarn in front, *sl1, YO, BRP. Repeat from * until the end of the row.
Repeats Rows 1 and 2 until cap measures about 7” from the cast on edge, ending in a Row 2 (it may be better to knit the length of the cap a little bit longer to avoid having a short cap).

Transfer sts onto 3 DPNs as follows: 20 sts on N1, 20 sts on N2, and 24 sts on N3. Shape the crown as follows: (number of sts left on N1/N2/N3 at the end of each row is shown in parenthesis)

Row 1 (MC): Take the yarn to the back, then *BRK, K2tog, YF, sl1. Repeat from * until the end of the row (15/15/18 left on needles).
Row 2 (CC): YF, *sl2, YO, BRP. Repeat from * until the end of the row (10/10/12 left).
Row 3 (MC): Take the yarn to the back, then *K2tog (which means knit as 1 st the sl2 and YO done in the Row 2), YF, sl1. Repeat from * until the end of the row (10/10/12 left).
Row 4 (CC): Wrap the yarn around the last st in the previous row, then slip marker, then *sl1, YO, BRP. Repeat from * until the end of the row (10/10/12 left).
Row 5 (MC): Take the yarn to the back, then *BRK, YF, sl1. Repeat from * until the end of the row (10/10/12 left).
Row 6 (CC): Wrap the yarn around the last st in the previous row, then slip marker, then *sl1, YO, BRP. Repeat from * until the end of the row (10/10/12 left)
After Row 6, redistribute sts on the 3 needles as follows: 12 sts on N1, 12 sts on N2, and 8 sts on N3).
Rows 7-10 (MC, CC, MC, CC): Repeat decrease Rows 1-4 (after Row 7, you will have 9/9/6 sts left; after Row 8 through Row 10, you will have 6/6/4 sts left).
After Row 10, redistribute sts on the 3 needles as follows: 8 sts on N1, 4 sts on N2, and 4 sts on N3).
Row 11-14 (MC, CC, MC, CC): Repeat decrease Rows 1-4 (after Row 11, you will have 6/3/3 sts left; after Row 12 through Row 14, you will have 4/2/2 sts left).
Row 15 (MC): Take yarn to the back, then K2tog around (2/1/1 sts left).
Snip off a 6 inch tail and using the tapestry needle, pull yarn through the remaining 4 sts and pull. Re-insert yarn through center to bring it to the other side of the hat and weave in all yarn tails. Block the cap, if desired and can add an optional pom-pom on the top.

Note: If you need to adjust stitches based on the gauge of your yarn/needles, this pattern, as written, should work for 64 sts or for 80 sts, 96 sts, etc (adding on 16 more sts at a time). If casting on 80 or 96 sts, you should end up with 5 sts and 6 sts at the end, which you can then pull the yarn through). If you add on more than 96 sts, for example, 112 sts or 130 sts, then you may need to do another repeat(s) of the decrease Rows 1-4 to get down to a small number of sts when you do Row 15, so that you can end the cap as described above. If you need less than 64 stitches, then consider using DPNs for the entire project (as stitches may not be enough for a circ needle).
