Here are the two bands I knitted , one leaving the first zig zag row on the back bed(pink) and one dropping the first row of back bed stitches and knitting on the front bed only(blue). The sizes are almost the same but the pink yarn was thicker than the blue. The second picture shows the bind off on the back. Either one is acceptable I think. Picture 3 shows how the teeth of the comb have to come up between the front bed needles in order for the comb to stay on and not drop off. Picture 4 shows the comb hanging behind the front bed stitches after pushing the back bed needles out of work .In the last picture you can see my needle selector tool sitting between the beds to keep the needles from popping up. All the front bed needles were down . I then took a loop and hung it on a front bed needle. Then I skipped a loop ( It does not look like I did but the loop closes when you stretch the one on either side) and I skipped a needle and did that all the way down the bed. Now I could have just bound these off but that would have taken too long and not as easy being on the front bed. So I hand knitted the needles for the row which did not take long. Then I brought up all the back bed needles opposite the front needles , knit a zig zag row and bound off the same way as the original.
So now it is your choice on how you want to make this, with or without frustration!
