Whether it is good enough or not, depends on who is judging it. All I can say it that I could not make it better than that.

So keep up the good work!

OK! Thank you both for the very quick responses.

I would say that V-92 thread is bordering to oversize. I bet V-69 is plenty good enough. I just decided to use the thickest thread my Pfaff 360 would take. I have repaired a number of seams of old sails and sprayhoods, and just thought that thicker is better. The V69 thread is probably what a sailmaker would recommend.

Sooo....

don't worry, be happy!

PS: Don't forget that the stretch in the middle of a junksail is much lower than in an ordinary sail of the same size. As long as you get a good boltrope on, which takes most of the loads, the rest of the sail will live an easy life.

Lay two pieces of cloth a foot square one on top of the other, and sew with straight stitch 3/4in from the edge (no more) to join them. Cut a piece of cloth a foot long, and wide enough to make a pocket 20% bigger than your batten diameter - I'm guessing 7in. Stitch this on according to method B, either straight or zigzag stitch. If you can do this, you can make a sail according to Arne's methods. [...]

Done. After making this mock up I have some confidence back. I understand the value of keeping the seam allowance (no idea what the sail making term would be, if there is one) for joining the panels smaller, 3/4", as you suggested. Thank you David, and Arne.

Now I need to get in the right state of mind to click 'order' and actually buy the cloth. The vendor does not seem interested in giving me any quantity breaks, so I think I may order 25 linear yards and then make a second order if (when?) I mess up a panel so bad that the cloth must be discarded.

I am ready to order some cloth. I am thinking I need 29 yards of the WM65. It is 61 inches wide. Is this a good amount for the 22 sq meter sail I plan to build, including batten pockets? Is this maybe too much or not enough?
