So you want to paint some easy flowers? Let's get started. First, I use a hard pencil (3-HB) which will let you erase your pencil lines. Don't make your lines too dark. (You will want to erase them before you add any watercolor). I use a kneaded eraser, letting my lines be just enough to know where my flower shapes are placed.
Next, I add the oval or circle shapes to where the tops of the flowers are going to be. I frequently use odd numbers of flower shapes, including the ones that might be small and hidden behind other flowers.
