I have been selling my excess machine knitting yarns on eBay as cones amassed are out of sync with years remaining. It's good to have the wool rehoused and create some necessary space. De cluttering is a long term process. The task has been made easier because every wool is catalogued. A sample of each is threaded and numbered in my file and at the back the weight and characteristics of each noted as well as which bag it is in. I am working my way through one or two bags at a time and reducing each by at 50% and in some cases (industrial acrylic) 100%, some going to charity shops. I love addressing the parcels with far flung UK destinations .
