I have not been the most active blogger these days, mainly because I am experimenting with paper jewelry and well, that is pretty time-consuming. But I do regularly update my Facebook Page, so if you have not taken a look, do drop by 
Though I enjoy making paper jewelry, there is nothing like folding a good solid modular origami to get one back in the blogging game! This modular icosahedron is a fairly easy model to complete and is folded from half a square. So 15 squares, cut into half gives the 30 rectangles required for the icosahedron. The base unit is Lewis Simon’s Triangle Edge Module.
Some points to note:
* I worked with coloured copy paper (80 gsm), which resulted in a good, sturdy model.
* If you are working with single sided paper, be sure to start with the coloured paper facing down (as given in the diagram).
* If your model is going to be tossed around (and believe me, this icosahedron very quickly becomes a football!), then be sure to add a dab of glue at the joints.
