I have collected magazines for many years, too. That's why I rarely buy one anymore. LOL Plus, I like the old ones better than the new ones. That probably says something about my age.
I have made quilts from magazines, but I think you need to be careful about the directions and measurements. Magazines make more mistakes than books. Make sample blocks first.
I still love them for inspiration and ideas, though. I store them in a funky little 'ol book case my DH made in shop when he was in Jr. High. Love it and the mags.
