What do you mean you don’t colour test your new art supplies before using them?! I use to never do it but now I love having a reference to look at on how the paints work on what texture when planning a new piece. Got some new watercolours to work with and they so purdy, never used tubes of watercolour before so we will see how this goes! #Watercolour #fabercastellwatercolor #fabercastell #colourtest #colourswatch
