I have a "running" nose, sniff, and my left brain is empty. Ideal condition for continuing the exercises. This is something we did in artschool, also while drawing nudes.
It is done on a Moleskine page which I cut out of the notebook, to smoothen the line in the middle. I held the little object in my right hand while I draw it from different angles with my left hand (non dominant) , (ink pen) not looking onto the paper, (only between shifting angles). Afterwards I put watercolour on with the right hand.
Have a nice day, here in Paris it is grey and it rains, sniff sniff atishoo, hatschi, hatchoum (resp. English/German/French sneezing:)
