Yeah, it's a realistic touch, for sure. Poor little unloved womrats.

I'm a knitter myself, so I'd have armies of sim knitters if they included it. Ophelia would be perfect as a knitter. It wouldn't have been that hard to include it - like you said, they already have that mesh and animation for Crumplebottom. It could work just like sewing, and they could end up with a scarf or an ugly toque when they were done. Then use the gift interaction to pass it off on a friend, and get upset when it doesn't fit them. It would be so great.
