This model was designed my Meenakshi Mukerji and appears in her book Exquisite Modular Origami.
I had previously made this model without the colour change, but having been on a jaunt to Hobbycraft with Caroline I had a lovely pack of coloured/white paper to try out. With a rainbow to choose from, I went for black. There was method to the madness though, as I thought the bold stripes in the model would look very striking in black and white.
Adding the colour change element only took two extra folds, and I completed the 30 unit model over several days, this time assembling as I went along.
The inverted sections mean that the modules hold together really well…which in turn makes fiddling the last few in tricky, but I got there without glue.
The finished model is about 10ins in diameter when folded with 5ins square paper.
