Decreasing on a raglan jumper.

On the startt edge, I normally do k2 tog. At the end edge, it s1k1, psso then k2. Have you tried that?

I think you have to do one sleeve decrease not knit 2 tog but knit 2 then slip the second k it stitch over the first.
Someone else might explain it better than me.

Yep that's a much better explanation

Google 'left leaning decrease' (essentially instead of knitting two together you have to ssk on the RHS)

Google 'ssk on the RHS in knitting'. You will see video showing how it is done

same as grandmattie here working on the knit side, I usually also slip one stitch at the beginning of each row, makes the edge crisp

Or you can knit 2 together through back of loop to make the stitches 'lean' the other way.

As Liz46 says

Beginning of row k2, slip 1, k1 pass slipped stitch over, knit to last 4 stitches k2 together k2.

I do that LadyGracy but slightly different on the first decrease:
k2, slip next two as if to knit, return the two slipped stitches to the left needle and k2 tog thru back of loop, then knit to last 4 stitches, k2 tog, k2.
That is a recent way I have found and it give a slightly neater decrease, imo

Sounds interesting CraftyGranny I’ll have to try it. Thank you.
