HI, I have made several of these and what i did was get the tiny strands of Xmas lights,(now is a great time to buy they are 1/2 price) You put the potpourri in the jar I also add tiny pine cones(at Micheals very inexpensive) and then with a pencil or thin dowel push the lights around the jar and you leave the end part hangin out(in the back) so you can plug it in. Then you cover the top with the doily!Because the lights are sticking out of the back you cant see the cord. They are real pretty and smell great, I use cinnamon potpourri for most of them.
Hugs Sandie
