I too had a lot of quilt magazines; mine, my mothers AND grandmothers. I went through what I wanted and asked at a sewing class I go to if anyone was interested. There was a quilt guild in the area that asked for them. I gave them boxes and boxes of them. They were glad to get them.
My sister also went through all her magazines too and took out the patterns she wanted and ditched the rest. But you still have to find a place to keep those too. I've let all my subscriptions lapse; there are SO many free, pretty ones online it makes paying for a magazines with more ads than quilt not worth the fee to purchase. And they put out fewer each year.
