Seam Series: How to Sew a French Seam Tutorial

French seams are perfect for lightweight and sheer fabrics, and are among the most popular of seam finishing techniques, as all the raw edges of the fabric are hidden in an elegant finished seam. It is also a great finish for seams that will be exposed, like an unlined jacket. French seams get a bad rap for being hard, but honestly they are incredibly easy.

The biggest hurdle is getting over the idea of sewing wrong sides together instead of right sides together at the beginning. It feels all backwards. Follow these easy steps and try French seams on your next project. You’ll soon be saying, “Oooo! La la!”

Many thanks for this info. I have been using French seams for many years and found them very difficult. Now I know the correct way I will continue to sew them in a less difficult way.

I’ve always sewn the first seam 1/4 inch and the second 3/8 inch that way you are sscure that you have enclosed the seam. It saves the step of trimming down the original seam and although you end up with a slightly bigger seam on the inside, does it really matter?

It doesn’t really matter, as long as the final total is equal to that of the seam allowance. I personally prefer a smaller amount left on the inside, since with lightweight fabrics the part left is visible from the right side. But in the end it’s a personal choice.

I enjoy reading this range of tutorials, as they reinforce the technique excellently with photos. I tried to tell a friend of mine what a french seam is, and I think she understood, but if I’d had this available at the time, I’m sure she’d have found it helpful, so I shall show this when I next see her.

Great tutorial. Thanks for the info. For the person who wanted a .pdf – I’m saving the article to my crafting Evernote folder. Evernote is unbelievably easy to use and allows you to save the article for viewing later.

Savannagal, you can try and select all of the text on the page and copy that into a tool like MS Word. Newer versions MS Word will then allow you save it as a pdf.

Thanks for sharing this great info. I have used French seams for many years, and now I know how to do it without all the bulk that I had. I love this for unlined jackets.

Can you use this technique in a curve, like a bag shape or hat shape for example?
thanks!!

Thank you for this wonderful tutorial! I’m preparing to make alterations to a second-hand wedding dress, which is kinda scary, as you can imagine! I’ll definitely be using this technique to keep it looking gorgeous and professional.

This is a very useful demonstration and easy to follow. Is there a way that you can do a French seam on the edge of a quilt instead of binding it? I can see how to do three sides but what about the fourth when you can no longer turn things inside out? Is there a trick to doing this? Many thanks

I want to sew together two parts of the same material vertically and I am searching for the least visible technique to do it. It will hopefully be a curtain in the end and I want to hide the seam as much as possible.
Can you recommend the best technique for this.

Thank you in advance!
