The needle felting tool with its lovely wooden handle works beautifully. I guessed the colours of roving I might need and ordered sight unseen over the phone with pretty good results. Only one dead duck and I'll be able to swap that with another felting chum.
The point (which I stuck into my thigh several times) of this needle felting exercise is repair holes worn in the heels of my much loved hand knitted socks. I don't want to have to do hours of mad stabbing motions all that often so I tried to make the replacement heels as substantial as I could. May have gone slightly mad with these. This is six layers of roving felted down and it is a little on the lumpy side. I have another pair with a three layer repair (try saying that with your teeth out) so I will compare, contrast and report back.
