We came across this cool DIY and had to give it a try for ourselves. This fun project comes together in no time with the help of a zipper and hot glue. Personalize the container with a fashionable zipper or use your favorite-colored plastic bottle for a chic look.
Measure an inch-and-a-half from the base of the water bottle, and mark with a pen. Use sharp scissors to cut away the bottom from the bottle. Do the same with another empty plastic bottle.
Select a zipper that wraps around the bottle comfortably. We found a seven-inch zipper fits perfectly with an 18- or 20-ounce bottle. Secure the zipper to the inside of one bottle with hot glue. Create small lines of glue, and press quickly while hot for best results.
Open the zipper, and attach the top just like you did the bottom.
Zip the container together, and you’re ready to store your stuff!
