Yes, some tips:

You are getting the cart before the horse. I think that you need to
learn a little about turning -- it is not as easy as falling off a log
or many of us would have lost interest a long time ago.

You need to develop some basic skills before you start to think about a
project, I believe.

There is a major difference between the skill sets needed for 'flat'
woodworking and those needed for turning. I came from 'flat' and once I
started turning I discovered that I really needed to give up the flat
work in order to develop skills as a turner.

Please remember that being ham-handed with a tool which you don't know
how to control and a piece of wood going around quickly could result in
a fat lip on you rather than on your lid.

I want to make some wooden lids for ceramics pots. Tthey should be
somewhat "dome-shaped," have a fat lip, and 4 to 8 inches in diameter.
I have access to a lathe but have never turned wood before. Any
suggestions as to what type of wood might be best, or any other tips?
