Cabled Coffee Cozy

Want to make something useful with your leftover yarn? Try a coffee cozy, or pillow for your coffee mug or the disposable cups. I knit this on straight needles instead of joining it in circular as I've seen in other patterns. This pattern can create an adjustable cozy if you sew on multiple buttons. The pattern is easy to modify if there is a specific mug you want it to fit. I used a bulky weight, but you can try a worsted weight (you would need more rows, but the smaller gauge would make the flap and the width of the body smaller--the variegated below is worsted). You can also add a color for the cables specifically to make it really pop (see mine here). I am not a professional knitter so please excuse any "strange" abbreviations or lack of clarity. I'd appreciate comments/suggestions to improve this and any design I make.

Materials:
Plymouth Yarn Baby Alpaca Grande (bulky)
US 10 needles
cable needle
button (you only need one, but can attach multiple buttons)

Cable Stitches:
LFC = left front cross = slip 2 stitches to cable needle and hold in front of WIP, P2 from left needle, K2 from cable
RBC = right back cross = slip 2 stitches to cable needle and hold behind WIP, K2 from left needle, P2 from cable

CO 8
The adjustable flap (increase or decrease the number of rows, increase if you want to add more buttons)
R1-3: knit across
R4 (button hole row): K3, bind off 2, knit to the end (6 stitches)
R5: K3, CO 2, knit to end (8 stitches)
R6-9: knit across

Row increases (increase or decrease the number of rows depending on the height of your mug and/or the weight of yarn)
R10: K1, k1fb x 2, K2, k1fb x 2, K1 (12 stitches)
R11: knit across
R12: K1, k1fb x 2, K6, k1fb x 2, K1 (16 stitches)
R13: same as R11
R14: K1, k1fb x 2, K10, k1fb x 2, K1 (20 stitches)

Cabled body (basically all rows are knit the knits and purl the purls, you just factor in the cable needle whether it is in front or behind the WIP)
R15: K4, P2, K8, P2, K4
R16, 17: knit the knits, purl the purls
R18: P4, LFC, P4, RBC, P4
R19 and all odd rows: same as R16
R20: P6, LFC, RBC, P6
R22: P8, LFC (knit all 4), P8
R24: P6, RBC, LFC, P6
R26: P4, RBC, P4, LFC, P4
R28-31: same as R16 (you can subtract or add rows to alter length very easily)
*the variegated cozy had an extra cable wound in and out...I was bored so I modified this design by just following the pattern...except I have no idea how I did it so I can't publish it. Feel free to experiment!

Repeat R18-24 EXCEPT R22 (or the R36 in the repeat) to make as follows:
R22/36: P8, RBC (knit all 4), P8 (this way, the cables alternate their crossing around your mug)

Row decreases (make this match your row increases for evenness)
R40: K1, K2tog x2, K10, K2tog x 2, K1
R41: knit across
R42: K1, K2tog x2, K6, K2tog x 2, K1
R43: same as R41
R44: K1, K2tog x2, K2, K2tog x 2, K1
R45: same as R41

Knit rows until desired length and BO.

Sew on buttons for a small, medium, and/or large coffee cup and enjoy! I'd love to see photos if anyone tries this!
