I did a MK 5 LD helmet. I was apartment sitting for a friend, and he has a 360 and Halo 3, so I threw it in and played through it. I started on Saturday morning and finished it early Sunday afternoon. I was laying around, watching Family Guy, when the idea came to me "I wonder if anyone has ever created a Master Chief costume"...so I fired up the Great Google and found that Indy Mougul video, which led me to this site. I spent a few hours reading through the stickies, downloaded Designer, and just printed the piece out, without scaling it or anything. I spend 8 hours building that helmet, and I still have it. It's WAY too small for me, but it's my first, and it will always be my first. I resined it just for practice.
