Serging Technique for Creating Smooth Hem EdgesSerger expert Gail Patrice Yellen shows how to neatly apply lace trim to hem a garment in the round.
A simple way to avoid an uneven hem when serging is to cut a “gate” in your fabric. This ensures the serger blade is set in the right place to trim the cloth from the start.
Any time you serge a circumference (like a hem), there is a slight jog that occurs at the beginning/end of your serging. Unevenness occurs at the spot where you angle the fabric to the right until the knife trims the fabric to the correct depth. This is the same spot where you must angle the fabric to the left to chain off and extract your work from the serger, as you finish serging the hem.
Serger expert Gail Patrice Yellen offers a quick solution to this problem as part of her article “Specialty Serger Feet: Part 1” featured in Threads #194, (Dec./Jan. 2018). The samples shown were made with the lace applicator foot and a hem lace application. In this article, Gail also provides tips for successfully placing the lace to match smoothly.
Cut a “gate”
Cut the starting gate in your garment to the same depth as you anticipate trimming off with your serger by about 1 inch long. In this case, the gate was 1/4 inch deep and 1 inch long.
Our example is shown for a lace-application technique, but the same principle works for simply serging around an edge. Don’t cut the lace trim to the exact length; you’ll apply it almost completely before cutting the end carefully for a precise overlap.
Line it up
Raise the serger presser foot and slide the fabric beneath, aligning the gate right up to the knife.
Ready, Set, Serge
Lower the presser foot and serge, trimming off 1/4 inch or your chosen gate depth.
This technique works with an overlock or rolled-hem stitch—as you finish the hem and approach the gate again, serge a small amount over the starting stitches and then shift the fabric to the left, chaining off.
If you are applying lace trim, as shown, pause your serging close to the end, a few inches from the starting point. Gauge the remaining length of unattached lace, and trim it to a slight, 1/8-inch overlap. Adjust this amount if it will help you arrange the lace trim to diminish the join.
Final Touch of Lace
Serge/apply the lace trim until you reach the gate again, and chain off. Trim the thread chains (beginning and end) and use a few hand stitches in matching thread to securely, but invisibly, join the lapped lace trim ends.
