The Outlines:
You need a waterproof black fineliner or marker, two brands I love are:
The classic Sharpie
Sakura Micron Fineliners in various sizes
The Colors:
Here’s where anything goes. My go-to are these, but feel free to include a variety of pens and markers when you feel like it:
Stabilo’s Pen 68 Max
Ecoline’s Brush Pens or DuoTip Markers
The Tape:
If you want to frame your artwork later on, test the paper-tape-compatibility first. Here are my go tos:
Painter’s Tape from Scotch Blue or Tesa
Washi Tape from Paper Poetry
