My sister (non quilter) asked me last night if I was afraid my fabric would get "shop worn" if I had it too long, how long do you have fabric before that happens? I'm thinkin with all I'm hearing about everybody's stashes, it must be safe for years??? After all, my hero (Eleaner Burns) says he who dies with the most fabric, wins!! She didn't say the most shop worn fabric, LOL Same for thread, how long does this stuff last?
