What are Reticula and Fragments?
Zentangle™ HQ loves and enjoys the interplay of grids and the metapatterns that adjacent or nearly touching elements create, by using fragments within each grid - simply repeated, rotaded, or mirrored.
GRID definition: a network of lines that cross each other to form a series squares or rectangles.
FRAGMENT definition: small sample building block made up of different shapes, such as: square, orb, triangle, seed shape.
