Our red superstar needle is a medium gauge with a star blade (four blade edges.) It is a favorite all-purpose felter, especially for felting with coarse or hairy wool. It works great for finishing down the fuzzies and for surface felting.
The double point red felting needles will speed up your felting until the felt becomes too dense to easily pierce - then you'll need your single point. The red quad point needle works best for large projects and flat felting.
