Stringing popcorn is a fun and festive way to decorate a Christmas tree. To get started, you'll need some fresh popcorn kernels and a needle and thread. Pop the kernels and string them on the thread, making sure to leave enough space between each kernel so that it can hang on the tree. Once you've strung the popcorn, you can decorate the tree with it by hanging the strands from the branches. Enjoy!
