Useful?

I was ironing my pants this morning. (Oh, stop that...if you know me well, you know I LOVE to iron.)

I am proud to admit that they are NEW pants.  New because I have lost some 25 pounds and needed smaller clothes before the cruise.  But that's another post.

So there I was, ironing...and I realized that the back pockets were still seamed down...so I opened them up.

Have I missed something in recent fashion?

This pocket is 2 inches deep. Now I usually don't use back pockets for anything, but if you are going to have them, shouldn't they be deep enough to put SOMETHING in them?

What would YOU put in a 2 inch deep pocket?  What COULD you put in a 2 inch pocket?
