My son, 16, is going to Germany this summer for a month. The director of the program said that each teen WILL wear his passport around his neck and under his shirt no matter how geeky it feels to them. I priced them and they start at $12. I made one for .99.
It was cool to design and make something quickly AND it used 2 zippers!
**He reported that after wearing this for 4 days the texture of the strap bothered him...otherwise it worked great.
