Right now I am wearing a multi-coloured, randomly-striped cardigan that I knitted about 3 years ago to use up some of my yarn stash.
It must have about a dozen different colours in it, and was a great way to use up small quantities of yarn, but my stash didnt feel any smaller afterwards.
And as a yarn stash tends to do, it has just kept growing ever since.
Ive just started knitting another cardigan from the same pattern, but this time just using two colours (I wouldnt quite have enough of the main one, which is a dusky pink), so will stripe it with a left-over skein of cream.
The pattern is lacy, and I'd forgotten how tricky I'd initially found it last time, so nearly as much pulling back as knitting going on at the moment.
Meanwhile, I doubt it will make much of a dent in my stash. I probably have enough yarn to knit dozens of cardigans if I could be bothered. Which if I am being honest, I can't!
