Polymer Clay Central is a great source of tutorials. I utilized the rose tutorial shared by Leigh Ross as well as two different leaf tutorials( 1, and 2 ) for my first attempt at a polymer clay rose cane.
I would like to make a face cane similar to Alice Stroppel's at Polymer Clay Etc. I've messed with a couple of things for the face and...well...they didn't go as well as the rose cane. It's going to require more time alone to focus. I wound up with lips that looked more like the internal organs of a cow. I knew how I wanted the cane to look...the lips cane that is...and trying to figure how to get them to turn out right, without a book or tutorial, is taking a bit of time. The same goes for the iris of the eye.
Maybe, I'll finish that sofa so it doesn't enter my head while I'm working on something else!
