The first piece I presented on this forum was a Manta bowl.

I did it gluing waste wood to protect the corners.
This one, I did turn following the "orthodox" method of Terry Scott with little wood pillar supporting the wings,
it's faster, but be careful with fingers.
Walnut, 8" diag X 2" H, wings thikness 1/8", Danish oil.
Enjoy with your turnings
I wish you a Merry Christmas
