Yes ... Bishop3D

Although the pots turned out rather well, the leaves/petals not so much ... 
I'm just looking for a better way. Maybe I just need to spend more time with 
a modeller to get the desired results.

Well now that you mention it triangles DOES sound like a better approach.

Some of the stuff I have read (unless I misunderstood) seemed to indicate 
multiple patches "glued" togeather to create the final shape ... I'm into 
new territory with this so I'm not standing by any of my assumptions at this 
point. If you think another method would yield better results, I'm open to 
exploring them ...
