Elecia WhiteFolded some origami with curved creases and miura ori pattern on cyanotype paper. Put it outside to get some sun. Washed and flattened, this is what they look like.
rhempel@logicalelegance that looks beautiful! Is cyanotype the same as what we used to call blueprint paper?
@rhempel No, it is marketed as sunorint paper, turns dark blue in tye sun, white where shaded.
@rhempel actually, yes, blueprints use the cyanotype paper… though I don’t know how yet
@logicalelegance I read the Wikipedia page for blueprints - there was a chemical bath used after exposure ... So notbquite the same :-)
