Mason Jar Solar Lights. Jars, stake solar light, double sided foam tape or glue. Find solar lights that have removable tops. Double sided tape used if light is smaller than jar ring-don't remove both sides of tape-on/off switch sometimes on other side. Glue light to top inside of ring. Set in sun 4-8 hrs. Another gal hot glued flat glass gems to outside of her jars rather than leaving them plain.
