Mending a knitted cuff

I'm in the process of mending a woollen jumper (sweater) for my husband. It is a gansey knitted by his mum and has seen better days. The wool is now slightly faded and has several holes developed, maybe from moth damage I'm not sure. Anyhow I considered it worth mending, and have mnost of the small holes mended now. I unpicked the collar slightly as that was frayed and shortened it. I'm not sure however how to mend the cuff on one sleeve. It is a 2 x 2 rib with several holes in one section. The rest of the cuff seems fine. There is a seam only a short distance from the holes. If it were straight stocking stitch I would probably pick up a section and patch it with a double layer, but I think that would end up bulky on the ribbing. Has anyone suggestions as to the best way of tackling this? It doesn't have to be invisible mending, I have similar weight wool, but not the same colour.

I believe I was taught to mend a sweater, each stitch needs to be caught.

What I can't remember is if this is done with thread or yarn.

I would normally go with as similar a yarn as possible to the original fabric. Slightly thinner may be better as the result will be less bulky.

It is the ribbing that is making this area more tricky for me - I would like to retain the stretch in the fabric if possible.
