I made the decision to cut back on my magazine collection earlier this year. I collect several different ones and although I have my favorites but still had way too many magazines. So I started going through them and copying my favorite ones for my personal use. I didn't want to tear out pages and ruin the magazine for someone else. I have 3 quilting friends who are part of my mini group and so we passed them around. The idea was that after all of us went through all the magazines they were then donated to our guild's free table. If you don't belong to a guild why not consider taking them to your senior center if there is a group of quilters that meet there. If no group there, take them to your thrift store. I still look for magazines there.
Think of it as making space for more fabric. Good luck.
