An Elegant Sufficiency has a tutorial on making these wonderfully useful bags. How do I know how useful they are? Well, I was one of the lucky recipients of a gift bag from Gill this Christmas and you can see from the picture above how I have put it into action. It is a great size for all those odd items that ... since I am an avid subscriber to the "pile" system of organization ... make my organization slide around on the desk and degenerate into messiness immediately.
I can assure you that they are easy to make, I found myself thinking "I can do that!" and I should do that because the organization method I most prefer would benefit from one of these bags in every room and just looking at mine makes me smile.
