You can work with the material you have- if you are a complete beginner - ask and I will let you know what you need - 3 colors, one brush and 4 different single sheets of paper.
My recommended minimum palette would be bright colors: W&N Artist - Winsor lemon, Permanent Rose and Winsor Blue (red shade).
Brush - Da Vinci Maestro, No 35 (extra point) size 4, 5, 6 or 7 depending on you!
Papers: *Fabriano Artistico, 140lb, rough,* Arches 140lb, fine, * Daler Rowney LANGTON, 140lb, rough or fine. One single sheet maximum of these and you are set to go. We will divide the papers into smaller pieces and go through that process as well - for this you need a metal ruler.
