Hi Jo,
As they say above welcome back and worth waiting for, I saw a pic of something similar a few years back and tried to make one this is my effort but with the lattice work as an extra, this is the only pic I have I called it a lattice Rocking Bowl from memory it was about 6" diameter. I made a bad choice using Oak but somehow managed to keep it in one piece.
I wonder of we used similar methods.
Cheers Martin.
