Nice vessel using some nice wood , I have never turned olive wood before , what is it like to turn ? That was quite tricky to turn by not having a complete circumference to the rim ( entry hole ), I have done a few like this and I know what it is like and prefer to avoid them if I can , it is always a bit of a thought inducing process knowing what shape to make the exterior of the form in relation to the voids and bark inclusions etc but you have done a good job here , also a simple profile if using highly figured wood seems to work best as you have here and like a few others I feel a different foot may work a bit better but not sure what style would suit it best .
