Learn about the differences between 30 weight and 40 weight embroidery thread
About Thread Weights
Weight refers to a thread's thickness. While it is somewhat counter intuitive, a lower weight number means a thicker thread. This means a 30 weight thread is thicker than a 40 weight thread.

Embroidery Thread Weights
The most common thread weight used for embroidery is 40 weight. Most digitizing programs are designed for using 40 weight. There are programs that can be modified to use 30 weight.
