Frequently Asked Questions (FAQs)

1. What is strong thread called?

As the name says, heavy duty thread is designed to withstand high tension and wear and it's generally thicker than regular all purpose thread. It can be cotton, polyester, a combination of the two, or even nylon.

2. How can you tell if a thread is strong?

Hold a strand of thread up to a light and inspect how many fibers fan out from the strand. A good quality thread will be tightly spun together so that few fibers deviate from the strand. It's not like a string of steel; you'll always see SOME loose fibers (kind of like rope).

3. What is the heaviest sewing thread?

Note: V 69 is the heaviest thread that will fit into a home sewing machine and is usually used for Boat Canvas. V 46 is a little lighter. IF YOU HAVE AN EVEN FEED FOOT, ROLLER FOOT OR TEFLON FOOT INSTALL IT. There will be less slippage of the fabric with one of these feet.

4. What is stronger than cotton thread?

Polyester is made to be stronger than most natural threads. It is important to avoid using polyester thread with natural fabric. Over time, the stronger polyester thread can break down the weaker cotton fiber of the fabric.
