Reticula and Fragments

In chapter 7 of the Zentangle Primer, there is a chapter on how to use reticula and fragments to make unique tiles. Often even though the fragment is the same, by mirroring it, or reversing it, different meta patterns can emerge . All of the reticula  have an R- letter and number running from R-A1 to R-L3 Each reticula is different, ranging from regular grids, to triangular and circle patterns. 

For my tile I chose R-C 1 which has a holibaugh type grid in one direction and a regular grid in the other. Both sets of lines are on the diagonal. I chose a rectangular fragment  Y 1 with a hibred  tangle in one corner.
I reversed and mirrored the fragment to create rectangles.  

Sometimes it can be difficult to keep the fragment the right way up on each of the grid squares. A lot of concentration and focus initially, but once the fragment is undeway, the process becomes a zen like meditation.
