leave it alone....

Having my Dad over for Christmas has been an ideal opportunity to give him a bit of tuition in weathering. Using one of his Christmas presents, I've demonstrated a few basic techniques using gouache.

Before:

After:

The clean patches on the Kernow models are just that little bit too clean. Both of the patches were brushed over with a grime mix made from raw and burnt umber and black gouache. When dry, they were brushed over with a large, soft flat brush to add subtle streaking.

Once satisfied with that finish, the white spillage was added and run over with the same brush, imparting a dirty tint to the white. This was repeated a couple of times to build up the finish.

Twenty minutes later, you have a wagon that is a little bit different to the rest. Go on, give it a go.
