Needle Felting is a craft that is easy to learn, inexpensive to do, and fun! You can create flat objects or three dimensional objects.
Felting Needles are straight needles with barbs cut along the shaft. When repeatedly pushed into a tuft of wool fibers, the barbs pull the fibers down, compressing and locking them together. The barbs are cut in one direction so that felting or matting together of the fibers will occur when the needle is pushed in and not when it is pulled out.
These were done in a heart cookie cutter shape with fiber I cleaned out of my drum carder - waste not, want not. So very easy!
