Yeah, that is obvious and fairly simple. but can't understand how from 57 one can get a totally flat model like the one of picture 59. I managed to flatten it but the tow triangles in circle are missing.
Finally after tearing 3 models of trying out different arangements I found a video tutorial on youtube and there is this kid that is doing these steps in a totaly different way but somehow is concluding the model just fine. Thanks anon.
