Mizusashi lid is opened with 1h, thumb on top, and leaned on mizusashi shomen.
Your thumb should be at 12’, on the opposite side of the tsumami.
- If you have short arms and that positioning is awkward:
- Take the tsumami “like normal,” with thumb on 9’ and index finger on 3’ of the tsumami.
- On your way down, rotate your hand so your thumb ends up on top.
- Return the lid back to the mizusashi the same way (but reverse). Start with thumb on top, end with thumb on left side.
