Working designs into a raglan sweater

I’m looking for help to put entrelac or fairisle designs into a raglan sweater pattern. I am currently working on my 3rd sweater from “The Incredible, Custom-fit Raglan Sweater”, and I would like to work some kind of design into the yoke, other than stripes, and I can’t seem to figure out how to make the designs work out evenly. I get stuck when the design overlaps with the raglan increases and throws my count out of whack. Thanks to anyone who might have ideas. Jerri (sammis_grammi):knitting:

I’ve just done this with a cable design on my first top down raglan. & using that same sweater pattern. (Usually I do set in sleeves bottom up)
After lots of maths calculations and frogging several attempts, I found the easiest way, in the end, was to chart the raglan out on graph paper, then you can see more easily how the stitch design fits into the increases and shaping. It takes some time but its worth it for the results. i don’t know how entrelac would work out in that situation, but the fair isle should be o.k.
