I was finally able to get some pictures from the event. There are only a few, but here is what I have to share.
As our normal practice space does not have a tea garden, we never get to practice this part. Here, sensei's mother is showing me how to use the tsukubai.
This is a snap of the inside of the chashitsu, set up for a summer-style ceremony.
This last picture is of most of the people in attendance. The member who owns the chashitsu and her husband, our sensei and his wife, and sensei's father are not pictured, as they were working in the mizuya. The woman in red on the far left is our sensei's mother.
It truly was a wonderful experience, and I am grateful for being able to take part in it!
