what do you do when you need to paint a pattern with water colour and you have two basic colors already underneath?
Correct... you use masking fluid (I use Schmincke although some papers don't like it... Torchon eg ... very bad idea to use Schmincke fluid).
You can make an educated guess what the test-pattern shows ;)
What do you do when you have to mask 61 centimeters with a size 0 brush?
Right.... you start swearing and try to find somebody giving your neck a massage afterwards (volunteers? :( ... )
I like the work thoug... when everything's done you can see how many hours are in one illustration. Hopefully.
