Felting pads are used to protect your surface while you needle felt and allow you to felt deep into your wool.  You can buy a felting pad at the craft store or your can make your own.  

Here’s how:

Get two squares of fleece material.  I usually cut mine to about 6 inches by 6 inches.

Place the squares together and, with a sewing machine, sew around the perimeter, leaving an opening to stuff the felting pad.  

Stuff the felting pad with toy stuffing.  I use Poly-Fil.

Your felting pad will look like a little cushion.  

Sew the opening of your felting pad closed.

Your felting pad may be a little lumpy at first, but after just a few needle-felting projects it will flatten out.
