FUMAO Polyester Thread Heavy Duty Bonded UV Resistant Outdoor Thread #69 T70 Size 210D/3Ply for Marine Upholstery, Leather, Sewing Crafts, 3000Yards Pack of 2 (Black)

I bought this to make some curtains for our camper. My sewing machine is normally used for canvas leather and other upholstery. With a few adjustments this thread worked great the fibers are not bonded. Threading the needle requires clean cuts not normal for me to use this kind of thread so I don’t know if this was normal. Seems strong enough to do the job no breakouts or slubs on the thread. It was much less expensive than the threads I normally use.

I purchased this to do some repairs to some large rips on vinyl boat seats and it worked perfectly. It’s heavy duty but not too thick to jar the seam holes bigger. I would definitely recommend this for boat seat repairs. Two large rolls for a low price is a great value.

So far so good! I ended up ripping some stitches on my kite boarding trainer kite first time flying, took a little time with YouTube videos on how to hand stitch, but haven’t had issues with it thus far, & that includes some gnarly crashes.

The thread appears to be good quality, but the bonding (It's bonded thread) is not as robust as American or European products. It's just OK for general use but not good for heavier or more abrasive fabrics like sailcloth that American bonded products would handle better.

Good value and lots of thread. Thread quality is lower than 5 stars, but not bad
