A beautiful DIY with plastic bottles. Tip: Use a medium hot iron and place it on the mouth of the bottle to connect the finish! Use baking paper between the Iron and the bottle, so you don't ruin the iron!
This would also be a cute dorm room idea. Also good for a gift for a girl leaving for college: package a set of fairy lights, clothspins, and small command adhesive hooks. Print this picture to include as a guide.
