The Brit & Co. beer bottle project is a great way to recycle old bottles. This would be ideal for college students who want to spruce up their abodes in an inexpensive way.
The only materials needed to put this together include, spray paint, painters tape, empty and cleaned beer or soda bottles, and puff paint. The painters tape is used to form the designs, and then you simply spray paint the designated areas.
If you want to create a more 3D effect, the puff paint can be used to create a pattern, and then simply spray paint over it. The nice thing about this project is that its versatile, as any colors can be used.
