I’m having difficulty with the edging of a shawl. I’ve knitted to the desired length and the next steps are provided below. I cast on 99 stitches and have followed the pattern to 50 inches. I did not cast off as instructed so need to know if I’m to use a separate circular needle to pick up the stitches and use both to knit the edging? Also, am I picking up 3 stitches in every 2 side stitches for the entire long side? I would appreciate any advice on this. Thank you.
"With the circular needles, pick up stitches along each side of the scarf. You have to pick up 3 stitches in every 2 side stitches of the longer sides and 1 stitch in every stitch of the shorter side.Knit 1 row in round. Place one stitch marker
or waste yarn 4 stitches before and after each corner stitch.
Cast on 5 stitches, knit them back towards the body, the last stitch of the edging should be knitted as k2tog with next stitch from the side of the body."
