Easy Guide to Sewing French Seams

In this easy guide to sewing French seams, I will show you how to hide raw fabric edges when sewing. French seams are the perfect solution for home sewers who don’t own an overlocker!

The French seam method requires two lines of stitching in order to encase the raw fabric edge. The method works best with lightweight materials. French seams create a more professional finish for your garments. It also reduces the risk of fraying edges so your garments last longer.

The following steps and measurements are for an intended seam allowance of 1.6cm or 5/8 inch, which is the standard seam allowance used in most commercial patterns and all Chiffon Jam patterns.

The first line of stitch

Place your fabric pieces together with the WRONG sides of the fabric facing together and the RIGHT sides of the fabric facing outwards.

Stitch 1cm or 3/8 inch from the fabric edge. A measurement guide can be found under the foot of most sewing machines.

Snip and iron the fabric

Trim the fabric edge by about half. This is critical to avoid frayed fabric edges getting caught in the second line of stitch.

Open the fabric up and push the seam flap to one side. Iron flat.

Close the fabric along the seam line, this time with RIGHT sides of the fabric facing together and WRONG sides facing outwards. Iron flat.
