I had to shell out $18 for a visor (from t-visor.com the website that sells nothing but boba fett visors!) Attempts to make my own weren't going well, and I realized that you sometimes have to suck it up and spend some money. The visor purchase did nearly double the money I spent on the whole thing. OK, I also spent another $5 on a suitcase which I cut up and resewed into the ammo belt.
I just finished "weathering" the helmet, here it is. Also, got most of the jet pack done, but I need to redo the paint on it. But hey, still three weeks to go.
I just saw this at gizmodo, what a perfect guide to the original costume.
