Hello.

I would like to design the table from the image. I am having some problems giving thickness to the snail shell.
I extruded it (wasn't that pleased with the result but... it was better than nothing) and tried to smooth it. The result was a horror because there were to many edges and maya took them as a height difference.

My question is:
1. How can i make the thickness better, without all the holes? (can i create edges between vertices)
2. How can i smooth the poly without making it look like a shell covered inside with spikes.

P.S. sorry about the question's noobness
