If you have been quilting for a while, you may already know this little tip, but if not, you might really benefit from it. Your fabric stash will look neater and will be easier to use if you will fold each piece uniformly.
Use your quilt ruler as a folding guide. Mine is 5" wide, but wider is fine. If your ruler is not long enough to span the folded width of the fabric, fold the fabric again lengthwise.
|Lay the ruler along one edge of the fabric.
|Leaving the ruler in place, start rolling the fabric around the ruler.
|Pull the ruler out some, leaving it in to the length you want the finished fold to be. I leave 12" in because of the depth of my shelves.
|Fold the "tail" over and pull the remainder of the ruler out. If you place the folded end where it is the end showing when placed on the shelf, it will look neater.
|Here you see the pile of fabrics in the first photo reduced to small, neatly folded stacks.
