In May of 2017, I learned about a workshop to build a tea hut designed by Terunobu Fujimori in Chino City, Nagano Japan.  I called the office and told them I was interested in participating. They asked me which date I could come.  I said "I can come every single day available."  

On the first day, Dr. Fujimori taught us how to make crinkled copper roof shingle.  The Chino Art Museum director, Mr. Tsyjino explaining where the copper shingle will be used.

We folded the copper shingles using a jig, then we beat them using wooden sticks until it looked like crinkled paper.
