@warpaint cyanotype is a uv-sensitive printing media; coat a sheet of paper with it, then expose it to the sun. anything that's blocked remains white, and anything exposed turns blue.
this print failed because i didn't get the exposure calibrated right, but here are some successful ones i've done in the past: https://modgethanc.com/instagram/af6a850eefe5b577053f21c0c78121a0.html
working from drawings is a bit trickier to figure out exposure; the ones in that link were made with solid opaque objects, which block light a lot better!
