I wonder if it has something to do with where we are at in our quilting journey. My friend who got me into quilting used to give me all her scraps (often not my taste, but still fun). She gave me less and less because she bought less, and she was never interested when I was given fabric from other sources. Me, I love fabric, especially when it's on sale!
But lately, I have felt less inclined to buy and more inclined to use what I have. I rarely see a must-have fabric. I see lots of collections that I pass right over. But maybe it's just me and that I'm satiated by my stash and I'm not as hungry for new fabric as I was in my early days. Or maybe it's just a phase – we'll see!
