Picking Up Stitches

I’m working on making a plush fish, and it’s time to work on the fins. I’m not sure what I’m doing wrong, but after I pick up the stitches and start working, the wrong side is always on the outside. Can anyone tell me what I might be doing wrong?

Here are the instructions:
Using CC1 yarn, pick up 15 stitches along the midline of the back near the tail fin. When picking up these stitches, begin at
the tail region and continue along the midline of the back towards the head region. Turn the work, and, using a new needle,
pick up another 15 stitches directly behind the first 15 stitches. Use Figure 3 as a guide to the placement of these stitches.
Join these 30 stitches into a round, and proceed:
Round 1: *[K1, P1] 7 times, K1, repeat from * to end of round.
Round 2: SSK, [K1, P1] 6 times, K2, [P1, K1] 6 times, K2tog. (28 stitches)
Round 3: SSK, [P1, K1] 6 times, [K1, P1] 6 times, K2tog. (26 stitches)
Round 4: SSK, [K1, P1] 5 times, K2, [P1, K1] 5 times, K2tog. (24 stitches)
Round 5: SSK, [P1, K1] 5 times, [K1, P1] 5 times, K2tog. (22 stitches)
Round 6: SSK, [K1, P1] 3 times, K1, K2tog, SSK, K1, [P1, K1] 3 times, K2tog. (18 stitches)

Thanks in advance!

Pick up the sts with the other side facing you.

I can’t pick it up on the other side because it’s stuffed. The body is already completed, so I can’t turn it inside out, and if I could, then the fins would be on the inside of the fish. Right now, the outside of the fish is the right side. The fins are also supposed to be right side. Unless you meant that I should do something else?

Not inside out. It seems like you pick up some sts, then turn and pick up more sts in the same ones, then you’re going to knit some sort of tube. So where you picked up would be on the inside of that tube.

The way I read it, you are picking up the stitches, turning the work, and picking up 15 more in a parallel line right behind the first line of stitches, thus as suzeeq stated, creating a tube-ish thing

I picked up the stitches without any trouble, but my problem is that when I start knitting, as the instructions state, the wrong side is on the outside. I’m not sure if it’s because of the way that I picked up the stitches or if there’s another problem. I’m just going to purl instead of knit. Sorry for the confusion!
