Sudden great diz afterthought

The diz I used yesterday sort of worked but didn't look exactly like Sara's work. I realized it's probably because the hole is a slot, not round. So I roamed about in in search of something round.

And found the butt end of a small safety pin does the trick. I'll try an even smaller one, since I now find that the diz aperture size influences the fineness of the eventual yarn. This had escaped me in the excitement of discovering the concept.

Once again Occam's razor comes through.  Good old Occam.
