Helpful tip for getting that department store look on your home christmas tree! Seems like a lot but most garland is sold in 10-20ft rolls and lights are sold in boxes of 1-6 hundred! Also you could do homemade ornaments.
Take glue and water, and brush the inside of mason jars. Adding water to Elmer’s glue helps it brush on easier. Add glitter of your choice to the inside of the jars, and roll/spin the jar around until the glitter coats the sides. Add a tea light after it dries, and voila!
