Zen Coasters 

So that night, a friend of mine asked me to make 4 handmade Zen Coasters for his colleague who was leaving town.  It was an urgent thing, and I had only 24 hours to do. So the next day, I sat through for 10 hours and completed the order. As much as it was exciting, it was stressful too, for I actively worked on the  'color' Zen Coaster for straight 6 hours, sipping water from the bottle nearby.
