That is based mostly on a design by Andriy Hechuev known as ‘Shy Triangles’. I discovered it on Instgram. 

The central a part of the mannequin is their shy triangles idea. 

It stumped me for somewhat bit. I did not notice at first that it was all triangle twists. A put up by Monika Hankova  revealed that data. 

The unique design solely folded the central space. After I did a tester it did not completely match on a 16 pleat grid. So quite than mess with folding a hexagon into thirds to get 24 pleats, I simply went with a 32 pleat grid. 

Personally, every time I attempt to do thirds on a hexagon it seldom comes out proper. I do know the steps. I simply discover them laborious to execute precisely. 

So, with 32 pleats, I added some further triangle twists to garnish the perimeters. 

The view of the again facet is fairly neat too. 

My crease sample sketch for the middle portion is included on the finish.
