A Note On Sewing French Seams

French seams are most commonly used for fine fabrics, we are using them here for a few reasons:

  • The seam is sewn twice, making the finished item more durable.
  • Raw edges are enclosed in the finished seam, to give a neat finish.
  • This gives an opportunity to practice French seams with more forgiving fabrics.

Please note: On fine fabrics the 1st seam sewn allowance is trimmed as a wider seam allowance is sometimes necessary for this step.  As cotton is being used here, a 5mm seam can be normally be sewn on a domestic machine without the fabric being ‘chewed’. The finished seams here will not be visible as per sheer fabrics, therefore a slightly bulkier finish does not present any aesthetic issues. The final seam on fine fabrics would be narrower, but in the interest of gaining insight into the technique, the seam allowances are not being trimmed following the 1st sew, unless you wish to. 

Important notes:

1.5cm seam allowance throughout, unless directed

For steps using machine sewing, straight stitch, backstitching at the start & end using stitch length 2.5 unless otherwise stated

Prepare your fabrics as per manufacturers care advice
