Thread Reference Guide
Thread Reference Guide - Superior Threads
What this page references is a description of the thread made by Superior, a description of the thread and recommended needle size and settings.
Typically the chart will give you information like "Use a #90/14 metallic needle. Reduce upper tension to 1. " (for their metallic thread). The best advice may come in the bottom row, where they list "water soluble thread" and advise "not recommended for swimsuits."
