Top stitched french seam

An easy seam for joining fabric when making tents and tarps.

YAMA recommends do-it-yourselfers use the top stitched french seam for ridgelines and seams between different panels of a tarp.

NOTE: YAMA does not use this process in production. Instead, industrial double needle machines are used to construct seams in a more efficient manner.

How to sew it:

Step 1

With right sides together, sew a basting stitch about 1/4” off the edge of the fabric.

Step 2

Turn the fabric so the wrong sides are together and so the fold lies along your basting stitch, then stitch about 1/4” off the fold.

Step 3

Spread the fabric so the right sides are facing up. Then fold over the flap and stitch close to the edge to complete the seam.
