The Comm Pad
First on my list of accessories was a comm pad. Not needed but I really wanted it.
If you are interested in making your own, the Nerdista has an inexpensive tutorial on how to make one from a plastic sign. You can get a sign from your local hardware store.
However, I chose to buy one. I purchased a flat one at first and when it arrived I just didn't like it. It was thick and heavy. My hubby also purchased the same one to use with his rebel pilot costume. He was able to trim a lot of bulk from his and make it work. I still didn't like it. So after hunting around I found one that was curved, and reasonably priced at Hole in the Ground Productions.
See the two side by side. Note how slim and curved the one is. It seems to fit my arm better.
Needless to say, it became my preferred one. I made sure to buy it before making my pocket. That way the window I cut for it was perfectly sized.
To paint it I just used sharpies. It is a challenge to get in all the cracks but I made it work.
It turned out really good!
