elting needles are barbed needles that can be used to interlock wool fibers. As the needle is moved up and down, the barbs catch the scales of the wool and entangle them, creating felt.   These needles work a little different than a standard compacting needle
 
This pack of fourSpeciality felting needles consists of two 38 Spiral Barb Needle and two 40 Spiral Barb Needle  .  The 38-gauge triangular needle is three-sided and leaves a smaller hole in the felted surface. The Triangular 40 sized  It felts more slowly than the smaller -gauge triangle needle, producing finer detail.
