Because these sheets have so much dark area, paper choice matters more than usual. Standard 75–90 gsm copy paper works for crayons and standard colored pencils. If you want to use markers, copic-style alcohol pens, or watercolour, step up to 120–160 gsm bristol or cardstock so the ink doesn’t bleed through.
Black is hardest on cheap printers — ink-jets can streak across large dark regions. If you have access to a laser printer, that’s ideal. If not, print at draft quality first to test, then bump to high quality for the keeper copy.
Recommended tools: a 0.3 mm fineliner for re-tracing details that the printer missed, a white gel pen for highlights, and a single deep purple colored pencil or alcohol marker to tie the whole 'magic' palette together across the page.
