I mentioned French Seams in my Café Curtain Post so we are back today to explain with a nifty diagram how to create your own French Seams. First, I want to thank Stacy from StacySews.com who taught me everything I needed to know about French seams.
French seams are a very easy technique of hiding your raw edges inside your seams to give a professional finish inside a garment or on the wrong side of a home dec project (like mine) so both sides look nice. I chose to use French seams to join my curtains panels so viewed from the outside of the window, you would only see a nice finish. I could have serged or pinked but I wanted something VERY nice, so I opted for French seams. French seams are a great couture finish and a way to make your projects extra special because they will look good no matter where you look.
French seams are also easy but there is math involved. Don't move! You can use a calculator. First choose the seam amount you want to use for the majority of the project. Let's use ½ in. for the example. You will need to calculate ¾ in. for each French seam (that is ¼ in. plus ½ in.).
To complete your french seams, first place your pieces wrong side together (you read that right, we are starting off backwards), pin and stitch along the seam like using a ¼ in. seam. Press you seam open and turn your fabric over the seam. Now you right sides should be facing and your first seam is sandwiched in the middle. Press again to get everything smooth and stitch along the seam line using a ½ in. seam allowance. Press your seam open from the right side. You will see that your raw edges are enveloped inside the 2 seams and the only thing visible along the back side is a nice, welt-like seam-a French Seam!
