1,000 yards to do a 4' seam - a bit of overkill don't-cha-think??
If you want some cheap v92 nylon to practice....
Note:For practice.
Just because it's free does not make it the thread to use for the final repair.
Any thoughts on dacron thread? It supposedly has good UV resistance and very little stretch, (but maybe that's not a good thing?)
What size needle would you need for a V138 Bill? I got the wifey a commercial Singer this winter that should be able to handle it.Do V138 if your machine can handle it. V138 is the heaviest and longest lasting but V92 is the biggest size most non commercial machines can use without hassles.
Do you guys use any special thread when sewing through clear plastic used in windows?
V92 is the normal thread used for boat canvas.

You want to use polyester thread...not nylon.

For Sunbrella, you really don't need to use larger thread than v92 and you have smaller needle holes.
V92 might be normal is some places but pro marine canvas shops in FL use V138 on Sunbrella. There's nothing wrong with using V92 but V138V makes better covers...stronger and longer life...it also punches though multi-layer reinforcement areas easier than V92. V92 last about 75% as long as V138 in UV conditions. Needle hole sizes between the two are a wash. The main reason shops use V92 on multiple layers of heavy material is because it gives longer sessions between bobbin changes...especially when using machines that don't (like sailrite's and clothes type commercial machines being used for canvas) have large bobbins. When doing production work this is major time gain and way less operator hassle. Customers have no clue about thread size and give zero value to V138 over V92 either.
Also, don't let advertising hype get anyone hung up on thread brand. I've purchased (since the mid 1970s) bonded dacron from many sources around the USA and never had a problem with any of it. I currently have four different brands (including sailrite's) and see zero difference between them in sewability or life span. About the only difference you see between bonded threads is on old thread where the lubrication has dried and makes the thread harder to keep uniform tension. A little teflon spray or oil on the spool brings it back to new.
There's no one right way but some are better than others.

Interesting but what does this have to do with Solittle resewing a couple of seams?
