Paint.

 I was mixing paint to make background papers for gelatine printing when I realised just how gorgeous the paint on the glass plate looked with the lovely colours & textures.

 This could have course been shown horizontal, but the paint suggested reeds or some sort of vertical vegetation.

                                          Definitely water here, looks like a calm sea to me.

                                        Perhaps another watery one, maybe a river this time.

Here are some of the background papers sitting out drying.  I want to over print on these so they really need to be quite dry. Of course the images of the wet paint above could be printed onto fabric rather than paper.
