I am trying to modiify a kid's lunchbox to carry my meds and test strips and log book.

As I have several large bottles, I need to figure out how to utlize the inside of the lid.

The only idea I have is to make a large pocket with small one sew to the front of it.

And make the back of it big enough to cover a piece of cardbroad and glue that to the inside of the lid.

Do you think that this will work or not????
