i purchased this to reinforce hand knit sock heels. it works like a dream. it is very fine and blends in with my yarn so well, nobody can tell it is there. now for the test of time. it should increase the life of the heels. i'm very pleased with my purchase.

Great for sewing with knits!
I first heard of "wooly thread" on Pinterest. It was recommended to help achieve better results when sewing with knits, to avoid stretched areas and so on, all the challenges you encounter when sewing with knits. Use the wooly thread in the bobbin, and regular thread in the top thread (needle). It worked perfectly the first time. Glad I bought it.

Best Wooly out there
If you're using a serger to fold over edges on fabric or need a serger stitch that will fill itself in then this stuff is the best. Its' strong, durable and gives consistent results. I've tried a few other brands but they aren't as good. It can be difficult to find a place that carries all colors so I just buy what I need online.

This is what you want!
This is what you want to use, to sew stretch / knit fabrics! I use it ONLY in the bobbin - regular thread on top! Hand feed onto bobbin threader, as you allow it to wind very slowly, so it doesn't pull the stretch out tight. This allows me to sew using my standard machine, with a straight stitch (set a bit longer, maybe), and not worry about threads breaking. I also use a walking/ even feed foot, also a great investment for knits and quilting.

Stretchy stretchy
I got the thread to use for sewing spandex to use as a body sock for my children. I didn't realize just how stretchy this thread is! I know it's for use with a serger, but I thought that it would still be possible to use with a regular sewing machine. I wasn't even able to get the machine needle threaded. The thread is a good quality thread; I just wasn't able to use it.

Beautiful soft elegant finished edging on many fabrics.
Wooley nylon gives a soft edging when used in a serger sewing machine. I make many polar fleece blankets and the edging is superb when Wooley nylon is used in the upper and lower loopers of the serger machine.

Great product
Oh my goodness! Hand winding this onto a bobbin has revolutionized my stretch sewing. I can use twin needles on the hem of a spandex type of fabric and it comes out looking like store bought. Using regular thread in the bobbin for that type of fabric gives awful results period I'm so glad someone on Pinterest gave a tutorial on how to use the Wooly nylon thread

Bad product
This thread falls apart really easy and frays immediately

El mejor hilo para tejidos elásticos. Lo uso todo el tiempo solo desearía que hubiera más opciones de color disponibles.

Ordered this item after reading an online tutorial about making a stretch item using this thread. Very good product which you use in the bobbin along with the top thread. I believe people use it with their overlocker or serger. When you wind the thread onto the spool you mustn’t pull it through the tension disc but guide it from the cotton reel holder with your hand and wind it gently onto the bobbin. It’s very strong and stretchy and is perfect for stretch fabrics. It also washes very well.

I bought this wooly nylon to use in my coverstitch machine lower looper. I had read that it will stop you getting skipped stitches on the bottom and it really works well. No skipped stitches on anything I hemmed since useing it. Very pleased will buy more

Una maravilla, es justamente lo que necesitaba, algo caro pero lo vale, quizás el único pero, sería que no hay disponibles los otros colores que necesito y me hubiera gustado pedirlos todos en un solo pedido. Lástima.

Pesima relacion calidad-precio. Jamas vuelvo a pedirlo.
