The next step is to attach the flap. Line your 10" x 10" piece of duct tape fabric up with the top of the bag body. You will want to be certain to leave a small gap between the bag and the flap to serve as a sort of hinge,
Lay a piece of tape half on/half off your flap piece.
Attach the flap to the bag, again remembering to leave a small gap between the bag and flap.
Secure the flap to the inside of the bag with another piece of tape.
Next we are going to attach the strap. Attach a piece of tape to one end of the strap. The piece should cover about 2 inches of the strap and hang off onto the work surface about two inches. Lay another four inch piece of tape on your work surface and cut it in half, leaving you with two pieces of tape approximately 1' x 4".
Attach the end of the strap to the side of your bag.
Use the two smaller pieces of tape to secure the strap on the inside of the bag.
Since this strap will bear a good deal of weight it is important to secure it with extra tape. Begin by placing one piece of tape over the outside of the strap.
Fold the edges of that tape over the side of the bag.
Place another piece of tape lengthwise on the strap to secure.
Place another piece of tape perpendicular to that piece to secure its edges.
Place additional tape on the inside of the bag.
Wrap a piece of tape around the strap where the small pieces join it.
Repeat this process with the other side of the strap being careful to not twist it when attaching.
Stay tuned for our fourth and final part where we will embellish the bag.
