One of my favorite seam finishes is a French seam. It encases everything neatly and makes your project look as good on the inside as it does on the outside. French seams work best for lightweight fabrics. I wouldn’t recommend them for heavier weights as they would add unnecessary bulk. So today I’m going to show you how to replace an ordinary 5/8″ seam with a French seam.
Ordinarily when you sew a seam, you would pin the right sides together and sew on the wrong side. With a French seam, however, you are going to begin by pinning the wrong sides together.
Next, stitch a 1/4″ seam on the right side. It will make sense in the end, I promise:-)
Now trim off any excess, but leave enough to keep your seam from pulling out. I tend to trim off about half of the seam allowance.
Press the seam to one side.
Now turn so that the right sides of you project are together and the wrong side is facing out.
Now stitch using a 3/8″ seam so as to encase your first seam in the stitching.
Press the seam flat.
Now you have a very neat and high quality finish to your seam!
I hope this was understandable! Let me know if you try it, or if you have any questions. I will do my best to answer them:-)
