A simple linen bag

Could it get any simpler?
Plain oatmeal colored linen, herringbone woolen twill tape (I wish I had bought more of it...) and linen woven tape for the handles. No lining. All inner seems are finished the French way. And there are two inner side pockets as well. One and the same pattern as this one and this one.

I got one remark, though, from K. and the girls: where's the decoration? Where's the little square? I wasn't intending on adding one - but what do you think? To square or not to square?

Note: I know some of you were interested in finding a copy of the book in English. The title of the book in English is: Linen & Cotton Natural Clothes - Japanese Sewing Pattern Book for Women - and it's written by Kyoko Sakauchi. I found one available here...
