Thank you so much for bringing my idea to life. Initially, the pastry chef even agreed to add separate bags of frosting so we could draw on the cake ourselves, but then we changed our minds and asked for an element to be added to the cake that we could then use as a starting point. The pastry chef responded quickly and was very sweet.
We decided to cover the price difference with candles, which the pastry chef personally ordered upon request. Very neat packaging.
