I got some greyish tackle twill to sew up some vests. I ALWAYS thought the twill was sewn with the matte side out and the gloss in. This just makes sense in my mind because the gloss side is very reflective and shiny and doesn't "fit" with the rest of the costume. I know that I read somewhere that it should be matte out, but I went to the wiki to check out the neck seal attachment and noticed that is says the gloss side should be out and the matte in.... Which is it?! I was hoping to sew a couple this morning, but I guess I'll have to wait.
