Here's some more about my previous post
Origami Emergency. If you haven't read it, you'll need to read it first for the following to make any sense.
The origami crabs have arrived safely, after a delay because the British customs office was closed for the weekend. Which reminds me: When I started telling a friend what I was doing, he asked, "What is origami?" So when I was filling out the export form to describe what I was exporting to the UK, I first wrote "two origami crabs", and then added "(paper, folded)" in case the export agent might think that origami is a species of crab.
I didn't quote from my email responding to Dave McKean, because I wanted to keep the story short and not boring to non-folders. But since many folders are reading this blog, I'll quote most of it here:
I have helped people with origami projects before, but not with such a time constraint! I think I can do it, though, but the requirement for white is a small concern, which I will explain.
Folding an object with many appendages, such as a crab, from a single square of paper without cutting is a complex process with many folds (424 steps for John Montroll's crab), which builds up many layers. To prevent bulkyness and a tendancy to unfold and look fluffy, such models need to be folded from a thin foil/paper composite. (On the Origami Database web page where you saw my model in gold foil/paper, there is a photo of a crab done in thin paper, which is not as crisp.) The malleability of soft metal and crispness of the paper combine for a good result.
I don't have access to white foil/paper, but the model can folded so that the white paper 'back' can be the 'front', and the foil side in back. I have 12 3/4 inch squares of silver foil/paper that I can use. (The foil side is actually a light-grey/silver speckle pattern.) My guess is that the model will be about 3 or 4 inches wide.
If you carefully examine the photo of the crab that I folded, you will see that a little white shows at edges at the legs. When I reverse the foil/paper, a little grey/silver will show in these places. From my experience in photographing origami, I predict that depending on the angle of the light, these edges will either look like grey shadow or silver highlights. I hope that this will be satisfactory. (You can daub these edges with thin white paint, if you prefer. I can include some extra paper to experiment with.)
If I learn anything more, I'll post it here. And if you find something, post a comment here. Details are often found in blog comments.
