Tools that changed my life... well, perhaps tools that made life a little bit easier are Tesa Precision Maskingtape and Liquitex acrylic gouache. The tape is really good to cut out shapes and forms which I then use as a template to paint on found, worn wood. That's difficult, because it's often an uneven surface. I tried all sorts of tape, but this one does the job best I think. The paint I just like it a lot. Before this I painted mostly with acrylic, but I really liked the matte effect of gouache. This combines the two, perfect for me.
