First cut out a strip the length you want your pouch to be. Make sure you are leaving room to cut off excess on the top and bottom later on. Its better to make it longer and cut off more then have it to short and need to start over. Cut another piece trying to keep the same length. Place that strip over the sticky area of the first strip. Remember sticky sides always together. Set aside and repeat getting two finished strips.
Step 2: Body width
The box I need dosnt have to be to big so I make another strip almost like the one before but I over lapped it with a finished strip. So add two strips to each finished strip you made before. Cut them about the same size and again place one strip down and then another over the sticky side.
Step 3: Body done!
Now place both pieces on top of each other. Line up one edge. If the other edge dosnt match up thats alright. Just make sure the gap isnt to much of a difference. If it is you might need to trim it a bit. Cut another piece and connect the bottom and top to make it one piece. An O shape.
Step 4: What size do you need?
The ends are ragged and we are going to fix that now. Cut off the excess from both ends. Place what you are making the pouch for on top so you can see the room you really need.
