Having run out of suitably shaded wool and dubbing for the body on Lady Caroline's ( tying 1/0 to 3/0), I'm attempting to mix my own Dubbing. I've bought some Roving or Felting wool Olive and Brown ( enough of the stuff for 3 quid or so to last a lifetime) to achieve approximately a reasonable shade. However I'm not sure what staple length to cut up for the dubbing. I've tried 20mm and 25mm but not too happy with the result. Is there an ideal staple length I should cut the wool to?
