Polystar Heavy-Duty #69 Bonded Nylon Sewing Thread - 1500 Yard Spool - White

I used this thread to sew passing and straps to a set of tree spikes I welded up. It's pretty strong and durable so far. Been using them for two months now.

I have an hard time finding heavy duty thread and when I do 2 small spools cost as much as this life time supply. The thread is very strong, you cannot break it with your hands it will cut you, I wrapped it around two butter knife handles and I am guessing it took 20-30 pounds to break it. I believe it is as strong or stronger than heavy quilting thread, but not as thick.

I reupholstered the seats and trim on my husband's boat. This thread is extremely sturdy.

Not that heavy duty, can break it with my hands some sewing

Great for sewing up my convertible top on my 350 Z . Regular thread would just not hold it together. Plenty of thread on the spool. I used it with a curved needle and it came out very well. I highly recommend this product.

Incredibly tough stuff. I'm no master of needlework, so I just threaded a strand of this stuff a few times around a torn-off shoulder strap on my hiking pack (which holds a LOT of stuff on a typical day out) and it's now good as new. This was a couple of months ago and it's still going strong. If the repair strands break I'll just put aside 10 minutes and thread a few more through.

Thread is double tough.

Using this to sew up denim and thick material.. feels like it lasts forever and good quality
