This is a pack of 10, 40-gauge, triangle-tipped, felting needles. Triangle needles are used for increased felting depth, creating deep puncture marks such as eye sockets, deep lines, attaching pieces and moving a lot of wool in the early stages of a sculpture. This is needle is preferred by most teachers and pro felters.
 
Wondering about gauge? The term “Gauge” simply refers to the thickness of the barb. There are many tables on the web that will let you convert from gauge to millimeters or inched but for the craft felter, its really not important. Gauge is a simple whole number that’s easy to remember. The confusing part about gauge is the larger the gauge, the smaller the shaft size.
