I made these projects at school. I have been told to sell them, but I am not really sure what they are worth. If anyone has a comment or opinion on any of these I would appreciate the feedback! Say how much you would be willing to spend. They are not for sale yet, but I just would like to know how much people think I could sell them for. 

My intention with this one was to put a plant inside. Its only  about  6" tall.  2 of the tubes at the top are hollow, and could let water and air go through.

I have been told this looks like a fairy house. It is completely hollow, but you can not tell unless you look from the bottom. This is about a foot and a half tall. It was meant to look like a tree house of some sort. 

This is a vase made from coils. We had to carve a relief at the bottom. This is also around a foot and a half tall.

This is a really neat platter I made. It was a technique called  sgraffito .  I painted the entire thing black with an engobe, and slowly carved away the white part to look like wood grain. The entire piece is hand carved, and has a hole to look like a paint palette. It has 3 legs that is stands up on.
