Today I share this fantastif video of Luca Costigliolo spinning with a distaff and a suspended spindle. He explains that as the spindle needs to be continiously turned that the drafting is done with only one hand, the left. This keeps the left hand at the distaff and the right hand at the spindle.
Later he talkes about suspended vs grasped spindles. He mentions that his spindle has a bulb on top for holding the half hitch so it should be used as suspended and that spindles with points like that of a great wheel should be used grasped.
Also of interest is the sling around his neck to hold the distaff, rather than relying on having it in the crock of his arm like I do.
