Start with the center back neckband. In the case of the back right and left are as you look at the back with the RS (right side or public side) facing you.
Pick up 3sts along the right side of the neck, then knit 24sts from the back holder and finally pick up 3sts from the left side of the neck. Then follow the directions for knitting ribbing.
Here’s a video for picking up and knitting that may help.
For the right back shoulder band, knit across the 22 held sts increasing 2 sts as you knit. then pick up and knit 5sts from the side of that back center neckband that you just knit. Again follow the directions for ribbing. The directions for the left back neckband are similar but you’ll start by picking up on the side of the center neckband and then go on to knit the held sts on the left side.
For the front neckband, there’s a mistake in the pattern. On line 4 where it refers to the “Back st holder” it should say Front stitch holder.
It’s a darling pattern. Please do post a photo when you finish and certainly come back if this isn’t clear or you have other questions.
