Melli's ABC Challenge: Letters Q and R

This is week nine of Melli's Wednesday ABC Challenge. She wants us to find the alphabet revealed either in nature...or elsewhere...but found naturally--unassisted by us. Todays letters are Q and R.

Q as found in the rubber sealing ring of this reproduction clamped glass lid Ball jar. This particular jar was produced in 1976 for the Bicentennial Celebration.

R as found in a community waterpipe.
