    Scott,
    there is a trap which is easy to fall in  -  the paralysing fear of making something which isn’t perfect.

    Relax, most cloths that are rot-proof and wind-tight will do. If Odyssey can be had at a reasonable price, then go for it. The sail will come out at about 7kg. It is on the stout side, but on the other hand, it will stand quite brutal handling and resist some chafe. Besides, it sews very well without pucking (at least on my machine).

    (.. playing in the cheap, available and good enough league...)

    I ordered small sample swatches for several different fabrics and also two yards of the POLYESTER RIPSTOP (DWR) - 2.6 OZ. I am not totally sure what I am going to do other than pull on them to see how they 'feel' and then maybe check that my sewing machine can stitch through several layers.

    Here are my findings for lightweight cloth...think parachute, kites, hot air ballons:

    A, B, C

    Turns out your linked source above beats them all.

    Thank you for the reply and the links to lightweight fabric. In your profile I see that you are using Odyssey III for your sail. Do you have any experience using lighter cloth for a junk rig sail? It seems like everyone is using Odyssey or an even heavier fabric.

    All four patterns are now lofted on painters paper including the rounding.

    Making one seam and pocket sounds like a good idea. I think I will need to get some seatbelt webbing first.

    It seems like the Swela Outguard that Jami used might not be available in the US. Does anyone know if there is a similar fabric available in my part of the world?

    The webbing only comes on after the sail has been assembled, so you can just as well start with cutting out a couple of panels, now that you have the patterns. Personally I join one panel to the next (after hemming luff and leech) as soon as it has been cut out. I like to see that all is well before I cut out the next panel...

    Thank you. I will keep that in mind. I intend to follow the construction methods in TCPJR book as closely as I can. I was thinking to make a small one-yard size panel just to make sure my 1970s Kenmore sewing machine can sew through the webbing and several layers of cloth before placing the big cloth order.

    I suggest you make up a short length of the seam between panels + batten pocket, and a short length of luff and leech tabling, using the same methods as you plan to use on the sail

    Got the top panel pattern drawn yesterday -- except the rounding. I hope to get that done shortly. Then only one more pattern to go! I am realizing now that the first, lowest, pattern I made is likely the most critical to get 'right'. I need to go back and check all the measurements on that again. With my cheap protractor the rise looks a lot closer to 9 degrees than 10 degrees.

    I ordered small sample swatches for several different fabrics and also two yards of the POLYESTER RIPSTOP (DWR) - 2.6 OZ. I am not totally sure what I am going to do other than pull on them to see how they 'feel' and then maybe check that my sewing machine can stitch through several layers.

    That ripstop looks worth a trial, at least. Can you get a yard or two to sew a test seam?

    This POLYESTER RIPSTOP (DWR) - 2.6 OZ is the closest thing I have been able to find to the ' 92 gm/sq m/2.7 oz sq yd textured ripstop polyester from Pennine Outdoor' (broken link now) that David T. first mentioned and that Jami J. decided to use.

    I think Jami's boat and type of sailing are very similar to my own. I would like to find a fabric similar to what Jami used.
