Then of course, you need the pen style felting tool above. (I already had the felting mat). If you are going to applique directly to fabric, place your fabric on top of the mat, then put the mold there. Fill the shapes with wool roving and needle according to the directions you get with the mold, very simple and very quick.
Now if you want to make your shape 3-D, then instead of fabric, you put a piece of computer paper on the mat, then the mold, and then needle as directed. When done you just peel the shape off the paper. The paper below is what I used when making a rose.
Can you see the dent I made in the wool roving??? Ha! neither can I. I think it's just like fabric scraps....multiplies in the drawers..LOL!!
But after I was done, this is what I had. A pretty rose, complete with leaves, and a butterfly! I think I'll do a little beading on them, and sew broach pin backs to them.
