Here is the easel all set up.
This is the piece of wood that holds the tripod shoe. Al put an insert with a 1/4-20 thread (the same thread that the tripod shoe uses) in the piece of wood and screwed in the tripod shoe.
The board hooked into the tripod base.
On the other side of the board is industrial strength velcro. We also put it on the back of a hard watercolor board. That way you can attach the watercolor board to the piece of wood and your painting won't fly away in the wind.
Here is the board for your palette and water. The slots on the right side are designed so that they rest against two of the tripod legs and that holds the board in place and keeps everything level.
Here it is all set up on the tripod.
And finally, here is the bag that I made to hold the easel. Mom's really excited to go out somewhere and use it. Now I just have to get one made for me. :)
