Starbucks cup embellished with the tangle Cyme. I used a Sharpie fine marker for the wide lines, and a Faber Castell permanent “S” for the finer lines. The shading was created with a Copic colorless marker which “melted” the existing lines so I could pull the diluted ink into the white areas.
Side view. The tangle Printemps was done by stippling with a Faber Castel “S” marker, and light shading made using a very pale blue Copic marker.
