To make this design, I started with a survey of all the bakeries selling donuts within my city. I bought from them and measured the dimensions oh their donuts, as well as their packaging boxes of various sizes. I then reached to a conclusion regarding the data I collected to identify the average size of the donuts. I timed myself folding the boxes and tried to identify the problem areas while packing for the customer.
Some of the bakeries I surveyed were, Baker's Den, TGB Bakery, Fresh 'n' Fresh.
