This is my girlfriend'a birthday. I have been thinking about surprise for her for a long time, so I decided. Let's make for her a surprise with cake. She really likes sweets and I'll make for her a big cake with her sketch. Sketch will be eatable and beautiful. I will draw on mastic her portrait and decorate with flowers, they are eatable too. Mastic is a substance which human can eat and it is not harmful for him. I hope that she will like this.
