Decreasing in Cable
This is the process I use when working the Gramps Cardigan (child or adult) to cross my cable stitches on a decrease row before actually performing the neckline & raglan decreases. See step-by-step instructions are directly below the video.
1) Knit your first st (the selvedge st).
2) IF your cabled stitches include any portion of the sts that will be used in the decrease (which would be stitches 2 and 3 of the row), sl sts until you get to your cable (this could be 0 or 1 sts, depending on where your cable begins).
3) Sl sts to cable needle, hold to front or back, sl next sts to RH needle but do not knit/purl these sts, then sl the sts from the cable needle to the RH needle as well. You should now be able to see the cable twist on your RH needle.
4) Sl all of the cable sts on your RH needle, one at a time, back to your LH needle.
5) Perform your ssk on the first two sts, then work the remaining sts in pattern and continue to the end of the row (or section, for the raglan decreases).
Once you get to the end of the row, you’ll want to parallel this side with your right front. I think its easier because you don’t have to do as much slipping back and forth, you can go ahead and work each stitch as you come to it and then when you get down to the last 3, you do your k2tog, k1.
In step 3, you are welcome to slip the sts from the CN directly to the LH needle once you get comfortable doing it. I only suggest taking them to the right first so that you can look at your twist and make sure you’ve done things in the proper direction.
