Milliput is very good putty for modelling and it is easier to work with it than with Green Stuff (but professional miniature sculptors mostly use Green Stuff). I make my sculpts always from Milliput and then add some details with GS or a mixure of GS and MS if needed. Just nowdays there are some problems with distribution of milliput in Slovakia, therefore I made my last sculpts from Magic Sculpt (although I think that Milliput is better).

When working with milliput use water just for making the surface smooth (and just wet your fingers or sculpting tools) because when you would use more watter during maybe the first half hour of working (really not sure about the time), you will have mud of the putty.

There are more types of Milliput, I tried just Millipit Standard and Milliput Terracota. I heard that the other types are not good for sculpting.
