The TUVWXYZ star is a complex modular planar model, designed by the amazing Meenakshi Mukerji.
The model consists of 7 intersecting stars, each star made of 6 arms. All the stars meet at the centre of the model. A total of 42 modules are required for the star, 7 colours and 6 modules in each colour. Folding the modules is quite simple, though time consuming.
Assembling the star is a good puzzle! I had trouble in understanding when to start adding the 7th colour, since you actually start with 6 colours. I eventually did figure it out :) The 7th star is the first one to get completed. In the picture, this was the orange coloured one.
