I suddenly remembered I wanted to do this whale shark pattern in this colour gradient and just happened to have quite a fair bit of yarn left - not enough to do another full project, but still too much to commit to scraps, so well that's convenient!
I thought I'd have to hold the milk cotton double, but it turns out that it works up slightly denser than the DK weight yarn...so it was fine by itself. There's actually a little extra bumpiness due to the differences in the yarn weight - the yarns don't match very well but it's cute anyway.
