Overview of Steps
This bag is constructed a little differently than most. The double fusible foam holds the body of the bag together. Therefore, the Outside of the bag is fused to one side of the foam and the Inside of the bag is fused to the other side. This is how it is held together.  In one of the last steps, you will be adding the Ends and sewing through all the layers. 
To state that another way... the Inside of the bag is not constructed separately from the Outside, inserted into the Outside, stitched together, and turn through an opening to finish... like many bags and purses.   
Instead, you will build the Body (long sides and bottom of bag).  This includes the outside and Inside pockets and handles. 
Then, you will construct the ends of the bag (short sides).  
The Body and the End will be sewn together to form a bag.  
Lastly, a top band will be constructed to cover the wire frame and hold it in place with hook & loop tape.
Overview of steps:
        Cut out fabrics, stabilizers, and foam (or batting)
        Construct Outside of Bag
            Piece Outside of Body
                Pattern Clarification: Don't fold over too much in Step 4. 
                    A scant 1/4" in plenty. Too much will shrink the width of the pieces and may make it more difficult in later steps.
            Fuse to Foam (the Outside Body will be wider than the foam).
            Add Outside Pocket
        Construct Inside of Body
            Piece Inside of Body
                  Pattern Clarification: Don't fold over too much in Step 21.
                      A scant 1/4" in plenty. Too much will shrink the width of the pieces and may make it more difficult in later steps.
            Add Inside Pocket
            Fuse to other side of Foam (now a sandwich of Outside, Foam, & Inside)
        Add Hook and Loop Tape to Body
        Construct Handles
            Pattern Clarification: I will be changing where the note about cutting down to the final length for the handles to before Step 25.  
                Cut to the final length (handle strip and fusible fleece) before fusing them together in Step 25.
       Sew Handles to Body
        Construct Bag Ends
              Pattern Clarification: Don't fold over too much in Step 33.
                  A scant 1/4" in plenty. Too much will shrink the width of the pieces and may make it more difficult in later steps.
               Fuse into a sandwich - Outside, Foam & Inside
        Sew Bag Ends to Body
            Turn Bag
            You will have a floppy tote bag after this step.
        Construct Top Band
            Apply fusible stabilizer, mark stitching lines, & piece together.
            Add Hook & Loop Tape
            Sew to Bag
        Insert Wire-Frame
            Wrap Top Band to Inside to hold frame in place.
