I have been using premo for ages to make my stuff, and have just started trying to learn to make faces in the hopes of making humanoid art dolls.
I tried several different doll-specific brands of clay (Cernit, fimo puppen), and all of them were too soft for the way I work. Kato clay is perfect for me. However, the first head I completed has cracks running all through it.
It was a small head (maybe 1 1/2 inches tall). No clay is thicker than 1-2 centimeters and it had a foil core. The cracks are all over the back of the head, and where I added clay on for the cheeks.
Any tips or thoughts on Kato cracking? I think I have only had my premo crack on me 1-2 times and I have made hundreds of projects.
Thanks in advance for any input!
