Not everyone is going to agree with the 501st CRL, If you have constructive in put that would be Appreciated, it would also help in many builds in the future and even the current members that are always upgrading. you don't have to be approved by the 501st, it is your costume to do as you wish, the 501st place the CRL up as a guide if you wish to improve on it fantastic! if you don't that is up to you. If you enter a 501st forum you will be given advise regarding the 501st standards.
Boushh is a Hard build not many people realise it, I applaud both of you its not fun. I do wish some live locally as I found another Boushh from another state that visited, I couldn't hide my excitement. I made her a few items (neck seal, cape,) as she didn't sew her costume. And that is how it should be, to be proud of another person's costume, encourage and point out what you can to help. No ones is better than another person's each is different, the only Boushh that is perfect is Carrie fisher's.
Boushh's costume is 90% made out of pig skin it also rips quite easily and comes in varies colours, Like other members looking at upgrading I have the colour of the tunic in Pig skin in a box and I have the leather for the pants in another just haven't worked out the Crinkle effect with the leather on the knees..
Many members are unable to get the pigskin or afford the costume made in it. Fabric look a likes work great. This also is used in the Scout CRL for the patches on the legs....Including other CRL's using the look "alike line" ones offering a different medium.
If you want my help I will go out of my way post up photos, keep an eye on your thread, suggest from my mistakes.
McBoushh Mine another members Boushh is on the 501st CRL . The bounty Hunters Guild Members worked hard on it.
