Ars est geometria iterata!
Going through old drawings, 2012 - details shown from 2 different drawings.
Border and tile study on dot grid paper
Micron 12 (0.7mm)
Metatron’s cube is 13 circles connected by straight lines. It contains all 5 Platonic solids. Stare at the center for a while and you'll see them.
Copic markers and multiliner
Zebra Clickart Marker Pens 0.6mm and Micron 02 edges. Just having fun
Dot grid paper, with progression photos
Offsetting the pattern by one square changes how it meets at the corners as you can see in this drawing
