BP Flowers was named such after I realized the completed design bore some resemblance to the British Petroleum logo if it were in 3D.
For this design, I wanted to apply the ombre technique to planar models mostly because I had never seen it done before and thought it would be effective. What you usually see with planars is a different color assigned to each of the planes in order to highlight the planar design. But I don’t always feel this is the most aesthetically pleasing application. In general any more than 4 different colors (not in the same family) is probably too many for any model.
Planars have a short history, most of the models have only having just been invented in the last decade. There is some crazy math behind it all and Meenakshi Mukerji seems to be leading the way. Her books provide the best resource we have on the subject including diagrams for each of the planar models.
The units themselves do not take long to fold, it’s the assembly which requires dexterity and patience to complete. Using the same brand of paper for all of the units is a good idea and will ease the process somewhat.
