This is a video of some miniature food that I made with polymer clay. You could also consider them re-ments. They were really fun to make and didn't take much time either (about 2 days). They are smaller than your finger nail and each individual piece is handmade, textured, shaded, etc. However, the extras (tea set dishes and clothes) were purchased from Hobby Lobby.
A few shots of the finished product (which are viewed in the video as well)
Like many of my creations, this was inspired by Stephanie Kilgast on flickr.
