I just have to put my two cents in here.. NEVER NEVER NEVER give a paying customer a cake that is not in a box or a plastic container. Once the cake is boxed by you and you know it is is the condition you want it to be... it becomes the customer's responsibility to keep it safe!!! I too have see people leave my place carrying cakes in all manner of tilt, and I cringe every time. but I have learned to close my eyes, shut the door and hope for the best!!
) Anyway.. unless you are the one bringing the cake to the affair.. always box it!!! Your cake is beautiful ! You should charge more than you did. (everyone always tells me I dont charge enough too
