Bring back wood inside.

A perfect way to give warmth to a home, is to decorate wall´s and other surface´s with wood panels. Use wood as the organic contrast to soften up a modern concrete house.  The choises are many now, fortunately not only pine and birch like in the ´70. I remember some horrific examples from back then. Stickwood has a great variety of planks made from natural wood which can easily be attached to your wall´s.
