Prompts 18-19-20 Self Imposed Impediments

18-Draw a food item from your FRIDGE.

19-Draw it again, but this time
TAPE your PENCIL onto the end of a ruler and
draw it while only holding the ruler and NOT TOUCHING THE PENCIL

20-Draw it one more time, only this time-
Put the item back & only use your memory-
ALSO - Use your less dominant hand ONLY.
