Raglan arm seam decrease in k2p2 rib pattern

I am having the devil’s own time with a circular knit cable mock neck. Every step is a crisis. I have now put the whole sweater incl. sleeves on the circular needle and am trying to do raglan decreases. Although I have followed the pattern slavishly (I think), it’s not coming out. What is the secret to doing this? The instructions have you put a marker where sleeves join and do the decrease every other row. This is what the instructions say: “beg 6 sts before marker and work sts as follows: k2 tog, k1,p2,k2 (marker sits between these sts), p2,k1,slip1 st as if to k, k1, psso”

I have no trouble doing this but it’s not coming out! what is the trick I’m missing? Help! Thanks all.

What happens, besides ‘not working out’? K2tog, work 8 sts in ribbing, then ssk.

Suzeeq, thank you so much. I have done two of the instruction decreases and “not working out” means that the pattern is wrecked and it looks like a mess. I’m dreading undoing it stitch by stitch, picking up what I drop in the process, counting and recounting but for that I guess there’s no substitute. Your instruction sounds easier and like the pattern will continue.

Again, thanks.

Remember, to keep sts in a ribbing pattern, knit the ones that look like knits and purl the ones that look like purls.
