The signature BananaSaurus Rex process? First, Rebecca gets up in the middle of the night, jolted awake by a new idea. Then, she thinks about it for a long time. And thinks some more. For about a month. Or six. She’ll carefully suss out as many details as possible in her head before setting her hands to work. Finally, when this busy mom of two finds a day with more than 15 minutes to herself, she sews the first prototype. That one might get thrown out. Or it might go out for “field testing” on Rebecca’s shoulder. Lastly, any small edits she’s thought up can be added. She repeats these simple steps half a dozen times and before you know it, a stunningly minimal, amazingly functional bag is born!
