Needlefelting 101 Demo-Felted Hearts

What's all the hoopla about needlefelting? 

Needle felting is the process of felting wool with the use of specialized barbed needles and without the use of water. Moisture is generally not well tolerated because the needles are barbed, unlike smooth sewing needles, and will rust. You can use applique's of wool to decorate your wet felting, crocheted, or knitted project and other fabrics.
