Hello again these are some of the things I did in 15mm scale in milliput.
I prefer Milliput to Greenstuff as it is more"solid" for want of a better word, I find GS remain to soft for my taste, whilst Milliput hardens solid & can be carved, filed etc.Having said that GS can be easily cut so it has its uses.
I prefer to do some work on hard putty rather than on soft.
I have used mixes of M & GS with various degrees of success but prefer to mix it with plasticine.
Still have to try Procreate.
