This bag is everywhere.  I had to try one for myself!  The original is tiny (but adorable!) so I enlarged it and added some extra size and length to the strap.  The fabric is a very popular one by Henry Alexander.  I actually found it at JoAnn Fabrics!  It was sort of a miracle since most of their fabrics are so crappy!

I should have added the magnetic snap like the pattern called for but Cal had used it for his "tool" collection and I couldn't find it anywhere!  I used flannel for the interior lining and a thrifted denim for the exterior lining (if that makes any sense!)
