Needle felting by hand is a great way to take out some frustration without inflicting damage :)
After punching the fibres I was left with this big fluffy cloud. Add to that a couple of pieces of black felt and a few stitches and voila, a sheep is born.
I've attached him to a piece of cotton fabric that I microwave dyed a little while back. Haven't decided whether he'll stay on this fabric yet, and I'm also thinking about maybe adding some stitch to the background fabric as it's quite plain looking at the moment, but I think I'll wait until I'm ready to join all of my sheep together first to see what I think will look best.
