Of the many sewing techniques that are possible with a serger, rolled hem edges are definitely one of the most popular. Most sergers offer a two-thread or a three-thread rolled edge — you will need to check your serger manual to see what is possible for your machine.

Two-thread rolled edges are perfect for delicate fabrics because only a minimal amount of thread is added to the garment. Lightweight organdy, batiste or silk chiffon are all examples of fabrics that need the light touch of only two threads. Consider using a rolled hem edge to finish sleeve or shirt hems on georgette blouses, or it is a perfect stitch to use on ruffles or flounce edges. A two-thread rolled hem is also lovely on lingerie items like slips and camis, too.
My favorite use for the three-thread rolled hem is for making cotton dinner napkins. This stitch provides a little sturdier edge finish than a two-thread rolled edge, which is more appropriate for firmer woven cottons. You can whip up a set of pretty napkins to take as a hostess gift in under an hour, and it is a gift that is sure to please.
A quick tutorial for serging a rolled hem on napkins
Thread your serger according to your manufacturer’s directions for a three-thread rolled edge.
Cut pre-washed quilting cotton or linen in squares. Sizes can vary from 16″ to 20″ or more. (I love 20″ square napkins!)
Test your rolled hem edge on a scrap of fabric and adjust cutting width or stitch length as needed to get the desired result. Both of these settings should be as small as possible, or close to it for a nice rolled edge.
Place your napkin right-side up under the serger, and stitch along one side for the full length of the fabric.
