What ever you choose to call them they are a quick an easy lathe project.
I have posted these in other threads but here are the three that I have turned so far.
These were turned from apple wood but you can use pretty much whatever you have on hand or can scrounge.

They were finished with natural Watco oil and then wax. Kind of a satin finish.
I do need to figure out a better / more consistant light for the photos.

Mike Peace also has a handout that you can download from his website. Mike Peace Woodturning scroll down and click on Twig Pot H.O.
I'll post some more details when I have time, maybe do another one and document the steps.
