Illustration Friday prompt is strong.
Birds' eggs are amongst the most elegant and strongest constructions in nature. As long as the shell has no structural defects, a properly cradled egg can hold enormous amounts of weight.
The whole eggs and strong thing was ringing a bell, so I had a dip in my archives. Sure enough, back in 2009 the prompt had been strong as well, and I egged it up that time too. You can see that doodle below.
I guess that I really find eggs strong... or consistently, anyway.
