FAQ

Q: What is the application of sewing thread?

A: Sewing thread is traditionally used to join cut components together using a sewing machine, thus providing seams with adequate strength, elasticity, and aesthetic properties.

Q: How strong is sewing thread?

A: Strength: The thread's strength is determined by the material, thickness, number of plies, and twists/inch. The strength of the thread is measured by its tensile strength (breaking force). A typical polyester 12/4 thread has a tensile strength of 17 lb.

Q: How do I know my sewing thread size?

A: Weight is numbered on the spool: A small number correlates to a thicker thread; a bigger number correlates to a finer thread. The three most common sizes of thread in the U.S. are 30, 40, and 50 wt. (For comparison, all-purpose thread is usually 40 wt.)

Q: How do I calculate how much thread I need?

A: By dividing the amount of thread by the seam length, we get the ratio of thread consumed. If we multiply this factor times the total length of seam, we can determine the total thread consumed for that seam. *Generally, 10% to 15% wastage of thread is added to the consumption derived.

Q: How to know how much thread to use when sewing?

A: A specified length of the seam, for example 3 inches, is measured and then the thread is removed by carefully unraveling the stitch. You can then calculate the amount of thread consumed in one inch and multiply this factor times the total length of the seam measured in inches.

Q: Does thread matter when sewing?

A: Sewing with the right thread is the key to any successful sewing project. Here's our guide to choosing them: Threads have come a long way since the caveman was sewing hide and fur together with fine strips of animal hide.
