I'm a crocheter and I keep seeing people talking/ using yarn winders and 'caking' yarn. 
I'm toying with buying a yarn winder, as I do like things to be neat, but I'm not really sure of the benefits IYSWIM.
I've got a blanket project in my to do list which is a many coloured, join as you go job so maybe just having a basket of small balls would be better than 15+ half used ones?
Tell me about your yarn winding please! :)
