I made things with using “KENTAI” technique. Last time I used 0.1mm-thick wood shavings to make a drinking cup with the technoque (cf. https://www.youtube.com/watch?v=Z8RtVfqUIUc). This time I chose rice straws to make a sake cup. The reason why I made it is I thought it’s wonderful to drink sake with the cup because sake is brewed from rice.
Step 1: Rice Straws
Use internodes (length: approx. 15~18cm) of rice straws.
1. Cut up an internode.
2. Open up the internode and make it flat.
3. Use rice glue (made from rice and 100% organic) to make a long strip (length: approx. 20m).
Step 2: Roll Up the String
Put a grain of rice into an internode to breathe life into the sake cup. And then roll up the strip by using the internode as an axis.
Step 3: Form Into Sake Cup With Kentai
Take advantage of "KentaiI" technique in order to form into a sake cup by gently pushing and sliding the coil with using fingers.
Step 4: Sake Cup!
After forming, go through a urushi (Japanese lacquer) coating process. It took about a few months to finish up.
