I chose Apoxie Sculpt for doing the wood grain on the Howdah.  Main reason for this is that it stays workable much longer than Green Stuff.


Side and front shots of the wood grain.  I think its turning out very good.  A week ago I probably could not have done this, but my hands this week are much more stable, less shaky, and my dexterity is coming back.
Only a bunch more planks to go, a few hours and it should be complete.  I've sketch out a bunch of stuff on the mammoth and will start a few things on it also using a mix of different putties.
