I have finally written up my polymer clay brand comparison trials. You can find them on my blog here
For me, for making canes I am now sold on Kato. The clay is very firm which helps to keep good definitions in the cane (once you have made it workable).
Here is one of the canes I have made from Kato clay.
This is a pendant with a crystal added to the centre
A smaller slice made into a simple bead
It is a great tutorial, very clear and easy to follow and I was stunned with the results I got first time. It is also a beautiful tutorial Sagit has really taken time and effort over it. You can see more of her work at her blog http://www.sigaliotdesigns.blogspot.com/
