Step 1: Materials
Duct tape in your favorite colors - I used what we had, which is run-of-the-mill, boring silver.
Step 2: Step One
Remove the tabs from the box
Step 3: Connect Box
Your box is going to be discombobulated at this point, so take two 4" pieces of duct tape and tape the sides of the box together.
Step 4: Wrapping
Begin wrapping the box with duct tape, one row at a time.
Each row should cover roughly a 1/2" of the previous row.
Continue until box is completely covered.
Step 5: Buttoning
Twist the paper clip to break apart. Thread the clip through your button's holes. Press the button/clip piece into the strap to mark where it will be placed.
Using the button piece, pierce a hole in the box to attach the button/clip to the box. From inside the box, spread the clip (like you would a brad) and cover with 2 layers of 4" square duct tape. This will prevent poking!
Once attached, cut a slit in the strap for a button hole.
Step 6: Strap and Done!
Measure out a length of duct tape, sufficient to your needs. Ex: Long for a shoulder bag, shorter for one worn at the bend in the elbow.
CAREFULLY fold the piece in half, sticky to sticky.
Cut off a 4" square piece of tape and attach your strap to either the outside or inside of the box.
Repeat for other side.
Voila! You're done!
