Zentangle Challenge #27 is for tangles starting with R - K - I. For Diane and Carolien's Weekly Zentangle Challenge.

I used Ragz, Keeko, K-Ning and Ixorus.
I've been having fun organizing my tangles in alphabetical order, and then demonstrating how to create them on the
Back. Then to shorten the demo, I use red for the first step, blue for the second step and black for the third step.2
