If you own a Bernina, some of them can take a felting foot attachment. You also have to buy a different sole plate but if you already have the machine you might want to check it out. Sewing with Nancy just had a woman on doing needle felting and it looked fun. She also showed a hand felter that you punch into a brush? Very interesting. I don't know about using it on a quilt but she was doing wallhangings and pillows.
