A lot of public places (nursing homes, seniors, libraries, offices, etc) will not accept old magazines now, for health reasons. Totally understandable!
And I can't believe that no one mentioned ... IRL neighbours and friends who quilt and sew!
As for yourself ... are you sure you want to be rid of them? A lot of the times the same patterns come around and are just made in new colorways!
Sit down and go thru them ... and at the least, cut out any patterns you wish to keep.
