I have been doing a lot of knitting and crochet these past few months. I snip the stray ends off and drop them into a little plastic bin as I work. Last weekend I delivered a needle felting workshop and when I got home I had a brainwave...... I wondered if the snips and scraps of yarn ends could be felted...... so I tried it..... Yay, it works. I put a very fine layer of roving down first, topped it with a thickish layer of snips of fluffy acrylic yarn, topped this with another fine layer of roving and needle felted it. Then I needle felted some fluffy acyclic yarn to make a teddy bear .
