Ribbed Hat: Cast on too many stitches. How to decrease?

Hi there. So I am making The Boyfriend Hat from Purl Bee in 1X1 ribbing. When I got to the set-up round for the shaping of the top of the hat I discovered that I had cast on 154 stitches instead of the 144 called for in the pattern! What to do? How to handle this?

Here are directions for the original pattern. I am making the smallest size:

Pattern
With one strand of Yarn A and one strand of Yarn B, cast 144 (160, 176, 192) stitches onto the circular needle. Place marker and join for working in the round, being careful not to twist stitches.

Round 1: *K1, p1, repeat from * to end of round.

Repeat Round 1 until piece measures 8 inches from cast on edge.

Shape Top of Hat

Set-Up Round: [Work 36 (40, 44, 48) stitches in established 1 x 1 rib pattern, place marker] three times, work in established pattern to end of round.

Round 1: *[K1, p1] four times, k1, k2tog, work in established pattern to 2 stitches before next marker, ssk, repeat from * to end of round. [8 stitches decreased]

Round 2: *[K1, p1] four times, k1, p2tog, work in established pattern to 2 stitches before next marker, p2tog tbl, repeat from * to end of round. [8 stitches decreased]

Repeat Rounds 1 and 2 five (six, seven, eight) more times. [48 stitches]

Next Round: *Ssk, [k1, p1] two times, k1, k2tog, p1, k1, p1, repeat from * to end of round. [40 stitches]

Next Round: *Ssk, p1, k1, p1, k2tog, p1, k1, p1, repeat from * to end of round. [32 stitches]

Next Round: *Ssk, k1, k2tog, p1, k1, p1, repeat from * to end of round. [24 stitches]

Finish Hat

Cut yarns and thread them onto a tapestry needle. Draw the needle through the remaining stitches. Pull tight and bring tails to inside of hat to weave in.

Would it work to just space out 10 decrease stitches (k2tog or P2tog) over a round to get it down to the correct 144 stitches and then begin the shaping?

Any advice would be greatly appreciated!

The trick is to find a multiple that will work evenly. In this case you can do one of the following-

Knit 5, knit 2 together around (aka k2tog)
Knit next row even
Knit 4, k2tog
Knit even, etc

Or

Knit 9, k2tog around
Knit next row even
K8, k2tog
Knit even, etc

The ending will still be the same as pattern is written probably. I would probably go with the 2nd choice, but it depends on your hat.

Thank you for the reply. This is a 1X1 ribbed hat. So I would just do as you suggest while keeping the established pattern?
