The construction steps are very similar to the regular French seam except for certain seam allowances have changed to accommodate a narrow completed seam.
A narrow French seam should be used for thin or sheer fabrics with medium to high fray rates. A narrow finished seam allowance will allow the seam to almost disappear in the garment.
Remember, French seams are best used on straight to slightly curve seams. They will not lay flat for seams that are extremely curved.
Please take note that a total of 1/2" seam allowance has been allocated for this pattern.
Pressing from the right side will allow the iron to naturally open your seam flat. Check out my Pressing Tips here.
