#softpastel Unison colour, Art spectrum on paper Canson Mi-Teintes A3
It turns out that dahlias and cosmeus are a family of Asters, so the theme is one - Asters;)
  The easiest way - to lay the tone with coal, at the end for petals I use an extra soft pastel Art Spectrum (set of light) is easy to apply even on a large number of layers, while leaving clear lines;)
