wool for knitting or crochet (BT47)

I am a member of Zero Waste North West. in N.Ireland. I have just started reviving my old knitting and crochet skills. I have begun to make ,scarves, mittens etc for sale to raise money for charities. I am nearly 80 so my pension does not lend itself to purchasing new wool. My mother used to undo lwoollens,from jumble sales but it is a painfully slow process. I need all types of wool, all colours, odddments or larger quantities left over from abandoned projects
