Playing With Soap has a helpful post, complete with photos, on layering Cold Process Soap. Click here to see it.
I do layers the same way: pour at a very pudding thick trace and try to work quickly.
I’ve heard other soapmakers actually make three batches (rather than separating one big batch into three parts), one right after another. The time in between batches allows the layers to harden enough to support the next layer.
