I'm going to be starting on my armor soon, and I came up with an idea for securing my armor plates: Button snaps, like the ones on jeans. I thought of them because I'm trying to find a way to get the armor to mount the same way every time, and to keep it on better than velcro will. I'm planning on putting the female connector piece through the back of the fabric piece (vest and boots) and attaching the male connector to the armor itself using gorilla glue. By doing this, the armor will be flush and secure against the fabric, but still be easily removed for washing the fabric pieces.
Has anyone tried this before? I've got a lot of faith in it (I've done other costumes in the theatre that used this type of attachment), but if it's failed people in the past, then I may want to try it on some inexpensive parts first.
