The yarn colourway design team at Rico that is.
They came up with what I think is quite possibly the most ugly yarn I've ever seen. It's Rico Creative Micro DK in the 001 (Rainbow iirc) colourway. 100% microfibre, which is what made me buy it as I'd never used microfibre before. I bought 3 balls, in different colourways to make dishcloths. The yarn is smooth, soft and makes great dishcloths - being microfibre, they do their job well and are much quicker to dry than cotton.
I did wonder if this yarn would look better knitted, but having looked at the project page for it on Ravelry, I don't think so. In fact, one Raveller who used this colourway for an Ishbel shawl named it 'Catsick Ishbel' which I think is quite a good one.
Oh well, I'm sure the worktops won't object and if we really can't bear the sight of them in the kitchen, I'll relegate them to bathroom duties!!
The other colours I bought were a brown, purple, green and orange which striped up not too badly (but I still wouldn't want a garment from it) and one that I think is similar to this one, but has dark blue, pink and grey in it. If it turns out to be another howler, I'll probably share it with you..... but if I'm feeling extra-kind, I might spare your eyes the torture!
