(here) and the proprietor is Sheila. She has some fantastic designs with a Science base to them and as a retired Math and Science teacher they just drew me in. As I went through her site I noted that she had asked for testers for this pattern back in late Fall so I figured she would have that under control but I sent her an email anyway and said I would be interested in future testing opportunities. I ended up proof reading the pattern and making a left and right facing crane. The pattern is beautifully laid out, well illustrated and very clearly explained. And it includes little hints too. I could see her Science background at play here. The cranes are designed to be done with two charms. The first one I made with some scrap material that was cut in a 5" strip. For the second one I figured I better stick to two charms. That worked perfectly.
When my daughter was in Brownies they made Paper Cranes and sent them to the war memorial in Japan. One of the boys in her class (about grade 4) made a stunning mobile for the school library with a 1000 paper cranes. It hung in the library for the rest of the time that my kids were at the school. So I have a bit of a soft spot for that particular design.
