Okay, so many of you know how to make a Duct tape wallet, so I will start from the part where you add the bow, and latch.

Cut a piece of duct tape about 4 and a half inches long

fold one edge to about the center of the piece

repeat step 4 and leave a little tiny bit of sticky tape

fold back ant forth in an accordion fashion to make the bow

it should look like this.

cut a 6.5 inch piece of tape,

cut it in half, lengthwise.

fold part way in
kind of like steps 3 and 4, but leaving more sticky space

wrap this around the middle of the bow, about 2-3 times
tightly so it doesnt come apart

Bring the loose end around in a loop,
and secure with another small piece of tape

add another piece of tape to the back of the loop, secure to the front of the wallet, close to the opening side

cut a piece of tape, about 3-3.5 inches and fold the corners in of only one side
making a kind of elongated trapezoid
this will be your latch
leave a little bit of the sticky part at the end

reinforce this with a few more layers of tape

attach the latch to the back side of the wallet.

cover it with another layer of tape , to make sure the latch doesnt fall off

if you want to, you can also add one to the other side of the latch, connecting the inside of the wallet to the latch, making it more secure

this is what the latch should look like after the extra tape is added.

this is the latch, completed

you're done!
