Adam Clarke on Proverbs 31:19

She layeth her hands to the spindle -

10. She gives an example of skill and industry to her household. She takes the distaff, that on which the wool or flax was rolled; and the spindle, that by twisting of which she twisted the thread with the right hand, while she held the distaff in the guard of the left arm, and drew down the thread with the fingers of the left hand. Allowing that spindle and distaff are proper translations of כישור kishor, and פלך pelech, this was their use, and the way in which they were used. The spindle and distaff are the most ancient of all the instruments used for spinning, or making thread. The spinning-wheel superseded them in these countries; but still they were in considerable use till spinning machinery superseded both them and the spinning-wheels in general.
