I finished it!  This is my sewing bag/tray.  The "Bionic Gear Bag"pattern was purchased from Craftsy and it holds a lot of stuff!  You can't see it, but I have my quilting supplies all within the zippered sections and the connecting pockets.
Sally Thompson of "Ripstitcher" is the designer.  She walks you through every step and has more detailed instructions on her blog.
I love it!  I plan to make several more.  Thank you Sally!
