DIY Apple iPad carrying strap

After you spent $499-829 on the iPad, another $500 on accessories and apps to make it semi-useful, how can you tell it apart from the other five in the meeting that got the same official Apple case, and cheap? There is no hole on the pad itself or the case, so cellphone strap/charm {I was thinking mini chalk pad or Final Fantasy Zack Fair/Cloud Strife's giant buster sword or Bleach 朽木 白哉 Kuchiki Byakuya's 斬魄刀 zanpakuto 千本桜 Senbonzakura } are out of questions (unless you want to use tape [which does not stick too well to that material], drill a hole, or use the super dorky dock lanyard).

It is a bit tricky to tie it, too loose, it may slip out, so be careful.
