A5 Sun Print Paper Kit Cyanotype Paper,40 Sheets Cyanotype Papers with High Sensitive Nature Sun Printing Art Drawing Paper and 2 Sheet Acrylic Panel,for Kids Adults DIY Arts and Crafts Project

This is a great set of prepared cyanotype paper. It's ready to go. Just add a negative image, some leaves, branches, anything that casts a distinct shadow. Leave it in the sun to develop then wash and the you get an image. These work exceptionally well. Highly recommended.

Short review: While the protective bag isn’t the highest quality and the process isn’t quite as simple as presented, you can get cool prints with this paper. It’s a fun art project to try or a good STEM activity to do with kids, as long as you go into it with a genuinely experimental mindset.Long review:It took me a few tries, just like printing old-school paper photos from film, but even after leaving these in the bag for three months, I got some decent prints.I actually used LED plant grow light strips, not sunlight, to expose the paper. I had a visible print after 20 minutes, but the color washed off under running water. When I exposed the print for about an hour and a half, only the middle of the print started to fade under running water. The best results I’ve gotten so far were with a 1.5-hour exposure and a little vinegar mixed into a tub of rinse water (in which no running water touched the paper). I suspect the shorter suggested exposure time would be fine in bright, direct sunlight.Caveats: The protective plastic bag somehow ended up with a hole in one seam although I certainly did not abuse the package. Fortunately, I had these stored indoors in a relatively dark spot, and they still work. The acrylic sheets are thin and came hidden in the middle of the stack of papers, so at first I didn’t know they were in there. Also, they come with a protective film on both sides, but it only says that in the Amazon listing and not on the package, so don’t neglect (like I did at first, doh de doh) to peel it off before trying to use them.You get more than enough sheets in the pack to dial in your preferred exposure and rinse methods, as long as you’re willing to research how the process works more than the instructions explain it, so despite the torn bag seam, I think these are a good value (at the current price of $8 for 40 sheets).
