How to make a Paper Christmas Star aka Origami Spiked Pentakis Dodecahedron or SPD

The Origami Spiked Pentakis Dodecahedron is an excellent Paper Christmas Decoration Star made out of 15 paper squares. In spite of the large paper size I was defeated by the last module after nearly 2 hours (!) of trying to lock the last unit in place each time another one dislodged Never mind, it is still a remarkable sound structure once (nearly) completed and you can not see which one is not locked anyway

IF YOU ARE NOT A PATIENT ORIGAMIST USE GLUE !! YES, again the G-WORD is used! Origafundamentali
