I used 5 inch round almond orange cake ganached in dark chocolate for ganache covered with fondant. Firstly, I rolled the grey fondant into a long sausage then I measure the length for the bag handle. With toothpick, I marked 2 holes on each side of the handle. and let it dry on the plate. I covered the whole cake with fondant then I cut the bag lid and place it on top of the bag. Later, I pushed 2 toothpicks half way into the cake for holding the handle. The buckle was cut out fondant painted in golden lustre.
For details, I marked some pattern on the bag with toothpick. Assembled the handle and finished the join with long thin sausage painted in golden lustre. For final touched, I attached a fondant rose and buckle. My mum loves it and the kids tried to carry the bag...it was so funny.
