I have only done one or two scrappy quilts but I am never sure just what to cut ahead. How does one know what size to cut unless you have a specific pattern in mind? I have huge variety of different cuts of fabrics given to me and I am at a loss as to what exactly I have to do. I usually end up buying fabric for a specific quilt so I hardly made a dent in my large stash. I suppose if I analyze the directions for several scrappy quilts, I will see a pattern of sizes emerge. I am fairly new so I am really ignorant of what I have to do. Thank you.
