I was just remembering the time when I was a bit bored and decided to erm upcycle some bits of old string in unuseable lengths into a dish scourer. Not only that, dear reader, but it was double-sided, one purple side made of softish hessiany string, the other made from bits of much harsher standard string-coloured stuff. So, a double-sided knitted scouring pad. 
Was tough on the fingers, that knit.
So come on then, confess all- what's your weirdest knit ever?
