How to Sew French and Lapped SeamsLearn to sew French seams or lapped seams, two new seams for you to try.
When you sew a basic seam, you may need to take an additional step to “finish” the seam allowances. Learn how to sew two seams that finish themselves: French seams and lapped seams. Finishing the seam allowances’ raw edges may prevent them from fraying and keep your project looking neat on the wrong side.
French seams are often applied to sheer or lightweight fabrics because the seam treatment is clean and narrow. French seams are neatly finished because the raw edge is enclosed between fabric layers. This seam treatment does not require you to adjust your pattern’s seam allowances. It may work best on long, straight seams.
Lapped seams are typically used with bulkier fabrics that will not ravel. Watch and learn how to lap the pieces along the seamline. The next step is to accurately topstitch through the layers for a neat and durable seam.
Once you’ve mastered French and lapped seams, you’ll find many occasions to apply them in your sewing projects.
