Beautiful thread and strong.
Great product, I build custom fishing rods here in Florida for a lot of people and have been buying threads at the rod building supply companys for 12 to 20 dollars for 100 to 1000 yards, I seen this thread and I have used embroidery threads before and loved it. This thread is beautiful and you get way more for your money. This thread is a size A for the rod builders that might read this. Bears a couple pictures of how nice this thread looks on a fishing rod. I have been telling all my rod building friends about this thread . I will be buying all my thread from this company from now on. As you can see in the picture,it takes over 1500 yards after thread to do that pattern.

Beautiful Color & Sheen
The thread performs beautifully on my 2007 industrial sewing machine. I am making velvet potli bags for my daughter's upcoming wedding. The color and sheen are perfect for my project. I highly recommend this thread, and will be ordering another color soon. The embroidery photo is my sew out of the Dragonfly Wildflower Design my daughter chose from HuongboutiqueCo, on Etsy.

Beautiful Color, Smooth Stitching, and Great Value Size
I ordered this Simthread 5500-yard embroidery thread for my mother, who does machine embroidery, and she’s been very happy with it. The silver-grey color is especially beautiful—it really made some of her holiday decorations stand out and look even more polished. I don’t believe she’s used this brand before, but based on her experience so far, she would definitely order it again. The thread feeds smoothly off the spool without tangling, which is always important for machine work. The large spool size is also a great value, especially for bigger or ongoing projects. Overall, a great find—beautiful color, easy to work with, and a reliable option for embroidery.

Used with free motion quilting
I tried this with free motion quilting and it worked very well. Nice sheen. I had no breakage, but it is very thin. It did shred when I had to take some stitches out, but for the money and taking a chance on something different, it worked fine. I just started using it for quilting, so time will tell if I continue. It certainly looks nice in free motion and there are many color choices.

Great quality thread, it’s so smooth and strong
There are so many things I love about this thread: - the colour is really beautiful, it’s a soft baby pink with great shine - it’s strong, does not break easily - it’s buttery smooth, glides through everything, and there are no burrs or snags - 5500 yds on one spool is fantastic and will last a long while - the plastic spool holder is recyclable (as well as the box it came in) and fits perfectly on my machine’s thread stand

Beautiful colour and great quality thread, smooth like butter
Initially I was wondering if this thread would be good quality, and I was pleasantly surprised! It’s beautiful and so easy to work with. Pros: - very strong thread, low stretch - extremely smooth, no pilling or knotting - glides through the machine and fabric like butter - the colour and shine is so pretty! - large quantity on the spool - the plastic spool is thick, strong, and can be recycled after you finish Cons: - you may need to purchase a thread stand or find a workaround if the spool doesn’t fit on your machine’s attachments

Excellent Quality Thread and Incredible Value for the Price
This 5,500-yard spool of light pink sewing thread is excellent quality and an amazing value. The colour is beautiful and the thread feels strong without being stiff or wiry. It runs smoothly through my sewing machine with no fraying, tangling, or breakage, even when stretched. I also appreciate how easy it is to thread into needles, making both machine and hand sewing quick and hassle-free. For the amount of thread you get and the quality, this is a fantastic price point. I’ll definitely be purchasing more colours in the future.

Perfectly worked with Singer
High-quality embroidery thread with rich, vibrant color. I used it with a Singer machine and it ran smoothly without fraying or breaking, even at higher speeds. The Christmas Green (S039) shade looks bold and consistent, making it great for both detailed embroidery and larger projects. Reliable and easy to work with.

Lavender Haze
This Simthread 5500-yard embroidery thread is a great option for machine embroidery projects. The large spool size is very convenient because it lasts a long time and reduces how often you need to change thread during larger designs. The polyester thread runs smoothly through the machine with consistent tension and very little fraying. I tested it on a few embroidery designs and the stitches came out clean with a nice sheen to the finished work. The color is vibrant and holds up well during stitching. Overall, this is a reliable embroidery thread that works well for both hobbyists and frequent embroidery projects.
