I work with two different colors - gold and yellow.
First I outline with gold. I use a tip number 3 so the line was better definited. Immediatly I flooded with yellow, made first a gold star in the middle - extended with a toothpich in the petals, then I made a white dot, also extended with a toothspick. All "wet on wet" so is quickly finished!
Later I try to use other colors, but the most I prefer is the yellow one!
