This one fell apart in the wash... I also squished the fur on the left side.
So I've been making these on my deck. The paper is sandwiched between two pieces of cardboard to keep it from getting exposed. Put it down, take the top cardboard off, put the subject on the paper as quickly as possible, while trying to keep it in my own shadow, and then get out of the way before my shadow gets recorded. Wait until it turns grayish (about 40 seconds), but not /too/ grayish... then take the subject off and put the cardboard back on as quickly as possible. Then put it in 1% hydrochloric acid for two minutes, and then wash for 10 or 20 minutes.

What's interesting is the original process produced a blue image with white lines, and the name "blue print" happened.
Then came the later process, which created blue lines on a white background.
Of course, all that's gone out the window with CAD software and todays large format plotting machines. Not as much fun anymore.

Hand-drawn drawings are extremely impressive. And their hand writing is so much better than mine... (-:
But the ability to edit makes "modern" drawings a whole lot easier to read. I have a schematic of most of the nuclear plant of the NS Savannah, and parts of it are cramped where they had to fit stuff in because they didn't leave enough room.

I got into Architecture because I love drawing by hand, and I still have all my drafting gear from those days.
Along came CAD in the mid to late '80s, and that was the transition to computer generated drawings. Yeah, easy to edit, but they lack the artistry and individuality of hand drawn documents.

Yes, cyanotypes are safe. There is cyanide, but it is tied up with other elements and not biologically accessible. Mike Ware's chemistry also includes ammonium dichromate, which is a hazard, but can be skipped at the cost of contrast and shelf life (I included it).
Don't drink it... but that applies to most things. (-:
