1) Single Roll: Mandala Crafts Bonded Nylon Sewing Thread

The Mandala Crafts Bonded Nylon Thread starts the competition strong with a claim: you won't be able to break it by hand! But does it live up to this statement? Let's find out.

Features and Benefits

  • Bonded Nylon - It offers greater strength than polyester and regular cotton, weather resistance, high heat tolerance, and high tensile strength.
  • A T70 Thread - A thick, tough 1000-yard thread but not too thick for standard sewing machines and needles. It works with both sewing machines and hand sewing.
  • Versatility - Use this thread for various projects like drapery, upholstery, heavy buttons, bookbinding, beading, webbing threads, mending outdoor gear, or sewing luggage and garments.


  • The thread's colors are slightly different from what's advertised.
  • The thread frays or gets knotted easily.

2) Set: Embro All-Purpose Heavy-Duty Bonded Sewing Thread

How would you like a colorful thread set for your projects? The Embro All-Purpose Sewing Threads come in ten pieces per pack and is designed for sewing leather, denim, outdoor items, and quilting.

Features and Benefits

  • 3-Ply Bonded Thread - The threads contain three internally bonded layers of polyester to meet the demands of tough sewing materials.
  • 135 Denier Threads - This thread weight is strong enough to meet your heavy-duty sewing needs. It’s also resistant to UV and saltwater.
  • No Exterior Coating, Outer-Bounding, or Wax - This prevents the accumulation of harmful chemicals that can damage your sewing equipment.
  • Color Variety - You can avail black, khaki, blue, ultramarine, saffron, cerulean, army green, emerald green, deep brown, and blue-gray threads in one set.


  • It's a strong material, which can be difficult to work with.
  • The colors are darker than advertised.

3) Single Roll: Coats and Clark Extra-Strong Upholstery Thread

One customer said, "this thread will cut you sooner than you trying to rip it off." That's how strong and thick the Coats and Clark Heavy-duty Thread for Sewing is, and here's why.

Features and Benefits

  • 100% Heavyweight Nylon - True to its name, the Coats and Clark Heavy-Duty Thread is made with heavy-duty nylon suitable for new or old upholstery work.
  • Bonded 3-Ply Thread - It's resistant to weather, abrasions, and UV rays. Therefore, you can sew both indoor and outdoor materials.
  • Superior With the Right Tools - If you want to make the most of this thread, the manufacturer recommends using a size 18 needle and then increasing the length of your stitch.


  • Some users believe it's not heavy-duty enough.
  • It's not the easiest thread to work with on a sewing machine. Even with a heavy-duty Singer, some users find that it’s still too thick to work with.

4) Set: Hal Consumables 6-Roll Heavy-Duty Spool Sewing Thread

Are you into stitching thick bags? Perhaps you know someone who makes and sells them and needs a sturdy string for product improvements. Then, look no further than the Hal Consumables Heavy-Duty Sewing Thread! 

Features and Benefits

  • Heavy-Duty White Cotton - Compared to polyester, cotton is softer, stronger, and doesn't lose shape easily. This thread is ideal for sewing canvas bags, feed bags, and flour bags.

  • It may break under tension and cause minor damages to your project.
