help with king cole pattern 4831

hi I am having trouble working out (keeping the pattern straight) on the increase stitches on shaping the sleeves on the cardigan , I cannot seem to keep the pattern correct can anyone help or has anyone completed this pattern?

I don’t have the pattern but generally when shaping in pattern, you have to give up the pattern stitch or part of it in the area of the increase or decrease. I usually work these edge sts in stockinette and then return to the pattern stitch as soon as I can. The previous rows work as a guide to the pattern on such rows.
That certainly is a lovely pattern.

Hi and Thank You for your suggestion I will give that a try ,
