HI JuneBillie, yes it is all connected. After everything is around all pieces and all the wss is rinsed off. (wss water soluble stabizer) Then you sew the back panel together with a zig zag, you zig zag the bottom of tray to the sides, but when you lift the sides up, it's much too tiny to sew together. So that's when I used a strong fabric glue to close the wall on the trays. After it has dried, then I use my fabric glue once again and glue the trays to the back panels. After it's all dry, close, and put lid on top. It was super fun to make.
