I bought a badge holder at our quilt show. It hangs around your neck and has a pocket in front with clear vinyl so you can put your id badge in it. The a pocket behind. I store a small pad of paper and my blue tooth for my phone and a couple of pens.
It's square and probably 3x3" made of beautiful batik fabric. I get so many compliments on it and people always want to know where I got it.
