D.Y.I ductape bag!

 Start by cuting cardboard into the sides, front, and bottom of the bag. Then cover with ductape

Once you have covered with ductape, put a piece of ductape on the side piece and tape it to the front and back. 

 It is a great touch to personalize it!

 I braided some ductape for the handle, but you can do anything.

 The finished product should look something like this!
