When I was in Naha, I took three Okinawan craft classes. The first was a coral painting class at Shuri Ryusen. A staff member explained how to do it and I was on my own to do whatever I wanted.
There were beautiful displays of items for sale in the shop.
After I was finished, I was offered coffee and a sweet in the lobby area. I'm not sure what the sweet was. It was a fried dough ball that was very chewy. Like many foods in Japan for me, delicious but unknown.
When I got home I had to iron the shirt to set the color. Here is my finished project, which was a gift.
