We've just put together a video of a new simple cat design, a joint project by Roberto Gretter and my partner Ioana Stoian. It's folded from an A4 sheet, although I suspect a US letter sheet would work as well. (A4 is taller and thinner, so perhaps trimming down an edge of the letter-size paper would help.)
Anyhow, you can see the model here: http://www.flickr.com/photos/ioanastoian/9493965206/ and here's the video: http://www.origamiforall.com/fluffy-origami-cat-how-to-video/ Enjoy! Eric Gjerde
