But worth it! Best to do in front of the Boob Tube, or chatting with friends. My mom recommended putting a bead at the bottom of each string so that the knot wouldn’t slip through the base of the crane. Thanks Mom! Oh, and she folded about 100 of them, so I can’t take all the credit. :)

Takes patience, there is really no good resource out there that covers it all. Best way to make one is to do it and keep evolving with what you learn! Here are my tips for making a giant camera obscura (about the size of a small washing machine):
1. make hole punch sized hole in a thin piece of material, like an aluminum pie plate. I at first tried a chopstick through the cardboard and that did not make a nice image. Great improvement. I think the formula I read somewhere said the aperture (hole) size should be 1/100 of the distance from the front of box to back.
2. Make a white background for image to fall upon with some nice white paper
3. Try darkening the other 3 walls by painting with poster paint or taping black plastic bags like I did, should reduce reflection from light bouncing off those walls and onto back, theoretically.
4. Make sure absolutely no light gets in. I had two holes for heads to poke in and old towels taped to the holes so that one could poke their head through without letting in light
5. Be patient. It works best outdoors and when you poke your head in it takes a while for your eyes to adjust.
6. Have a friend around who will jump around in front of the hole for you so you can have an even more surreal experience, watching an upside down “movie” of your buddy on the inside of the box! My Brownies (I did this for a camp) had a lot of fun and one even ordered from inside the box “More Dancing!” They then wanted to do handstands on the grass to see if the people inside would see them “right side up”.
