That's the stuff!!!
A word of advice---DON'T ADD TOO MUCH WATER! And cut the water needed in half by also adding acrylic paint to tint the clay. Use cheap craft store-type paint. AND, and white glue at the same time. The more water-based glue and paint you add, and the less water you use, the less it is prone to shrink or "lift" off the base.
Add a small bit of water, paint, and glue together, and mix it up with your hands (wear one of those rubber gloves you can get at auto shops in bulk). It should be the consistency of like, thick oatmeal--if you've ever microwaved it too long, that's what I"m talking about.
Remember--the less water, the less shrinkage and the quicker it dries.
