If your thread is pulled tight on the underside and not forming an even stitch then (counter-intuitively) it’s usually the top thread tension that’s wrong. Sometimes very lightweight fabrics such as sheers can get dragged down into the machine so it’s a good idea to use a straight stitch plate.
What do the 2 numbers on sewing machine needles mean?
The numbers on a sewing machine needle denote its size. Every sewing machine needle has two numbers divided by a slash, for example, 90/14. The larger the number, the thicker the needle. The larger number to the left is for the European sizing system, which ranges from 60 to 120.

What is a 16 100 needle used for?

Why is my thread bunching underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
Should I stitch in the ditch before quilting?
Stitching in the ditch between borders helps stabilize the fabric, maintaining straight lines and preventing distortion. If you choose to stitch the ditch, do it as the first step before adding any quilting design in the border or sashing.
