For me it depends on the quilt. For a baby quilt, I like to use coordinating fabrics because these are usually gifts that I want to look well finished and planned. If it is a quilt for me and I am going to be quilting it, I first want a subtle print to help camouflage my quilting stitches as I am just not that good at quilting yet-and I prefer the wide fabric if I can find it just to avoid having the center seam. Lastly if it is a special quilt that I plan to send to my LAQ expert, I look for a lovely coordinating fabric that will look good on the quilt and show off her beautiful work.
