Frequently asked questions
What is a 120/19 needle used for?
A 120/19 needle suits very heavy canvas, upholstery, vinyl. Largest household Universal size in the Schmetz guide. Pair it with Heavy thread thread as a starting point, and test on a scrap of your fabric before starting the project.
What do the numbers 120/19 mean on a needle?
The first number is the metric size and the second is the US size. The metric number is the blade diameter in hundredths of a millimeter (80 = 0.80 mm). So a 120 needle has a blade about 1.20 mm thick. Higher numbers are thicker needles for heavier fabric and thread.
What thread goes with a 120/19 needle?
Thread makers suggest Heavy thread thread for a 120/19 needle. The eye must let the thread pass without shredding or looping. If thread frays, breaks or skips stitches, move up one needle size or switch to a topstitch or embroidery needle with a larger eye.
Which needle types come in size 120/19?
In Schmetz sizing, 120/19 is available in Universal, Hemstitch (Wing) needles. Choose the type by fabric: ballpoint or stretch for knits, jeans for denim, microtex for fine wovens, and universal for general sewing.
How often should I change a 120/19 needle?
Many sewists change needles every 6 to 8 hours of sewing, or at the start of each new project, and immediately if the needle hits a pin or starts to make a popping sound. A dull needle causes skipped stitches, snags and puckering long before it looks damaged.
