What you need:
Watercolour paper, portrait format, from 300g, Faber-Castell pencil Castell 9000 HB, Faber-Castell watercolour pencil Albrecht Dürer Magnus, Faber-Castell Art & Graphic water brush, Ruler, Eraser
Draw guide lines with the Castell 9000 HB pencils. This creates a symmetrical picture and can be erased later.
Pre-sketch individual letters with the thick tip of the Magnus watercolour pencils. Then paint over them with the water brush.
The more water you add by applying pressure to the tank, the lighter the colour will appear on the paper. This creates beautiful colour gradients!
Allow the paint to dry well before carefully erasing the pencil lines. And you have lovely watercolour lettering!
