I started working on this one a few days ago. The isocohedron consists of only 30 individual units, all a variation of the windmill base. The colors I used were red (10), orange (10), green (5), and white (5). I used solid colored fabriano (craft) paper 15cm x 15 cm.
The units were very quick and easy to fold but the assemble was a little challenging. I had to use tweezers. 5 units together in a ‘5 petal’ assembly, then each one of the unit petals were linked together by another unit, forming a 3 unit ring.
