Make 1's in ribbing

I have to add 6 M1’s in my ribbing for sweater sleave. But it changes the pattern. Can someone tell me the best way to do this. I cast on 48 stitches and need to increase next row to 54. The next row is a cable.

Since you’re going to be increasing at the ends of the row, the incs won’t show so much. Work the first st, inc then keep to the ribbing pattern - knit the knits and purl the purls.

Is this the situation: You have done the ribbing and they want you to increase 6 stitches in the last row of ribbing and then move into cables? I think I would use a simple backward loop working the last row of the ribbing stitches just as they come and throwing a backward loop over the right needle in these places. K4, (M1, K8) repeat to last 4 sts, M1, k4. Don’t change the order of the stitches, just work them in pattern as they come. Try this on a little swatch and see if it works for you.

Another idea. Usually they don’t have you do a cable twist on the first row of a cable set up. If that is the case you could do the increases on the first row of the cable set up row, just past the ribbing. The way I suggested, math wise, above would make the increases evenly spaced, but you could put the increases where the cables are going to be as well, only adding the 6 they call for. You could use a lifted increase or a raised increase, or even the backward loop. Personally I don’t like a Kfb much in most cases anymore because it leaves a bar across the front and so is more visible.
