I often purchase fabrics with no particular plan. And I just returned from a Hancock’s of Paducah trip! My purchases included multiple neutrals to use for backgrounds, multiple wide backs (108 inch ones) for quilt backs, polka dots and stripes and checks just because I love using those in quilts, lime green and dark pink fabrics because I seem to use a lot of those, and some Tula Pink fabrics. One or two yards usually works for me except the neutral backgrounds . For those, I generally get at least 4 or 5 yards. It is harder when you don’t know what you’re going to need. I have a lot of fabric, but it seems I’m short on something when I go to actually make a quilt pattern.
