Chocolate and Yellow Roses

I had an order for chocolate and vanilla cupcakes with chocolate and vanilla buttercream frosting. It was an order of 24 cupcakes but I had to put four in a box and the rest in another. I wasn't sure what sized box would fit 20 cupcakes, so I just got the boxes that I have available and fit 10 cupcakes into one box. As you can see, the box is still too big. I was very worried that the cupcakes might topple over. But I got a call after I delivered them, saying they were great and going like 'hot cakes', so I guess they were okay! Hmmm....but should I tape the bottom of the cupcakes to the box in future?
