Coin bottle-pouch
Also, plastic bottles could be transformed into an innovative “coin pouch”. Take two plastic bottles with the same dimension and shape. Then, cut the bottom of these two plastic bottles with a cutter. The next step is to get an old zipper or buy a new one. With a heated needle, make small holes in the bottles so you could sew through them. Put the zipper in the same way you see in the featured image and start sewing with a strong nylon string.
