I had a de clutter before Xmas - took everything out of the swing room so I could paint. Put boxes in the family room, and things I knew I'd never use again in there - including cross stitch and lace making materials. Then spent a few nights going through magazines. Ended up keeping about a dozen, the rest went in the boxes.
My sister does volunteer work at 'The Olds' as she calls them, so when I went down there for Xmas I loaded up the car and took them down to her. When she took them over they thought all their Xmas' had come at once.
Maybe you could look at donating them to one of those places. Most of them are on pensions and can't afford to buy them. I know the lady who took the lace making materials was in seventh heaven. She could make lace, but couldn't afford to buy the pillows and bobbins.
