I used some regular packaging string and some yard with texture. Wrap the string around the jar tightly and tie a knot. Now wrap the string around the rest of the jar tightly criss-crossing and overlapping until you like what you see. Then just tie the end to the leftover string where you started and cut off the ends.
Place the jars onto your covered surface upside down and spray paint them evenly with 2-3 coats. Make sure to let them dry for 5-10 minutes in between coats. Once they are fully dried just cut the string in one place and unwrap. Now you can place a tea light inside and decorate away :)
I think it would also look cute to wrap some twine around the bases of the jars for some more texture.
I love the different effects the skinny string and the textured yarn create. The jars that were wrapped with the thicker yarn look like they have puffy clouds floating in the sky.
This project is also super cheap since the jars were free and I had the string and yarn on hand, all it cost me was a can of spray paint. They would also make great little gifts, just tie a ribbon and bow around 3 and you're ready to go.
