Thank you for all your kind comments. Dry felting is getting wool roving/tops (unspun clean fluffy wool from sheep/alpaca) and then pushing or 'needling' it into a woollen blanket to form a design. The needles are very thin and barbed, so as you stab at the wool, it pushes and felts it together permanently. I drew the design on to the woollen blanket piece and then needle felted it. Before sandwiching and binding I washed the top, so any marks came out and it helps to flatten and further mesh everything together (I did my usual fret about worrying if it would fall to bits). You do have to watch your fingers and you need a sturdy brush (looks like a rectangular scrubbing brush) under the project to protect your lap/surfaces, but very easy to do.
