We save undamaged beer bottle caps for a variety of projects. Returning from a recent cleaning trip at Scarborough Faire, we had a great big collection – all of which needed washing. Marita Beth in her CDO way, laid them all out to dry evenly spaced and aligned. I turned one over and snapped the photo before turning it back over. Her CDO scares me. 
Cheers.

LOL!
Honestly…weren’t you tempted to leave it…or to just nudge one of the caps in the middle just a touch out of place?
As soon as read “laid them all out to dry evenly spaced and aligned”, my inner Puck reared his head and cried out for just one chance to nudge one out of place…
