Lot's of times through our travels we pick up all kinds of small carry on items and they end up like this.

The best way to organize is take everything out and see what's really there.  Separate " like thing" together, discard or give away what is not needed and then replace in a neat and orderly way.  This allows you to find what you need, when you need it!

Putting small items in clear packaging can make it easier to find when you need it.

Nice and tidy, onto the next project!
