Re: German artist supplies
I know you can get most German art supplies in the US, but they are a lot cheaper here. Faber Castell, Schmincke and Hahnemühle immediately come to mind. Schmincke has wonderful watercolour and gouache paints (pretty much all ranges, but their Horadam line is their artist grade stuff), Faber Castell for coloured pencils (Polychromos) and Hahnemühle for really good paper (I love their Britannia as a low cost, but surprisingly good quality paper for practice and their Czecanne and Leonardo papers are just wonderful high quality cotton papers). Depending on where your wife is in Germany, she might want to see if there is a Gerstaecker store nearby. They are a huge art store chain and have a huge range at reasonable prices.
