Essentially this is a duct tape box, but what makes it unique are the way the sides collapse down and fold upon themselves to close the top.
It makes a great change purse. Its durable and easy to use and because it is made from duct tape, it can really take a beating. You can make it more stylish by using different colors of duct tape. I've used mine for over 2 years and it continues to work great. No more digging around for loose change for me.
Total time for this project: Approximately 30 minutes for construction

Step 1: Gather Your Materials!
1) A roll of duct tape
3) A ruler
4) A pen or pencil that can make marks on duct tape
5) A large heavy book or flat object to place on the completed change purse to initially help it hold its shape.
6) One sheet of printer paper
Step 2: Measure the Width of Your Duct Tape
In this example, the duct tape is exactly 2 inches wide.
Remember, the wider your duct tape, the larger your change purse will be.
Step 3: Cut Four Strips of Duct Tape
In this example the width of the duct tape is 2 inches. Each strip is cut to about 7 inches (2 in. X 3 + 1 = 7 in.).
The reason you want to cut this longer is so we have some room for error when we start sticking the tape together. Remember we can always trim later.
Step 4: Stick 2 Pieces of Tape Together, Criss-cross.
IMPORTANT: Remember that for this to work, the 2 pieces must make a perfect square corner (90 degrees). If there they are taped together at any other angle, you will not be able to tape the sides together.
NOTE: I was able to eyeball this step, but if you can't, you can use a sheet of printer paper as a guide to make sure the pieces are square.
Step 5: Cover the Back of One of the Pieces With Duct Tape.
This will make both sides of this one piece "non-sticky".
Step 6: Covering Up the Rest of the Sticky Parts
You should now have a duct tape cross, both sides of which should have no sticky parts showing.
Step 7: Cutting the Sides to the Proper Length.
Once you have marked each side, cut on each mark. You will now have each side cut to the proper length.
Step 8: Cut Another Long Piece of Duct Tape.
In this example, I cut a 9 inch piece (2 in. X 4 +1 = 9 in.)
This piece will be used to tape all the sides together to make a box.
Step 9: Attaching All the Sides Together
Start by taping your long strip that you just cut to one side of your box. Make sure that the tape is straight and that it starts right in the middle of that side.
Bring up a 2nd side and push the 2 edges of both sides so that they are flush with each other, then gently stick the tape onto the 2nd side.
A tip here is to try and keep the top edge of your long strip in line with the top edge of your box side. If you don't then your long strip will start to drift and you will get a small sticky edge that will show . You could easily trim this, but I find it easier to make sure it is lined up correctly in the first place.
What you are doing is taping all 4 sides of the change purse together. When you are done you should have the end of your long strip overlap by about 1/2 inch.
Step 10: A Duct Tape Box
The next steps will show you how to make it collapse upon itself.
Step 11: Making It Collapsible - Crease Each Side.
Do this for all 4 sides.
Step 12: Fold All the Sides Down Together
NOTE: At first the duct tape will be stiff. You will have to hold one side down while folding the next.
Step 13: Help It Retain Its Shape.
One is to place your folded change purse under something flat and heavy for about an hour. This will help to reinforce the creases on each side. Another is to put it in your pants pocket empty for a few hours. Your body heat will help the tape to become slightly malleable and help it to retain its folded shape.
Step 14: Enjoy!
To open: Simply grasp the tops of 2 folded down sides that are opposite of each other and pull. The change purse will pop right open.
To close: The change purse will naturally want to close on its own, but you can help it by giving the top a sleight counter-clockwise twist.
You now have a functional and very unique looking change purse. Digging around for loose change will be a thing of the past. Enjoy!
