Frequently asked questions
What is a 100/16 needle used for?
A 100/16 needle suits heavy denim, canvas, upholstery, leather. Aurifil pairs 12 wt with 100/16 or 90/14 Topstitch. Pair it with 12 to 30 wt (use a Topstitch needle for 12 wt) thread as a starting point, and test on a scrap of your fabric before starting the project.
What do the numbers 100/16 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 100 needle has a blade about 1.00 mm thick. Higher numbers are thicker needles for heavier fabric and thread.
What thread goes with a 100/16 needle?
Thread makers suggest 12 to 30 wt (use a Topstitch needle for 12 wt) thread for a 100/16 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 100/16?
In Schmetz sizing, 100/16 is available in Universal, Jersey (Ball Point), Jeans / Denim, Microtex (Sharp), Topstitch, Leather, Hemstitch (Wing), Super NonStick 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 100/16 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.
