Start by estimating how large you'd like your star to be. If your balsa wood is quite long, you may need to cut it in half. If you do need to cut it, measure to halfway and use a hand saw to cut.
Form a star shape with your dowels.
Wrap twine over each point that the wood meets to secure the shape. Secure the twine with super glue and leave to dry.
Wrap the fairy lights around the dowel, leaving a trail of lights that will create that shooting effect.
It's time to determine where you'll hang your stars! Map out where the star will go on your fence and the three ends where the lights will trail the star to get that shooting star look. Once you know where you're going to hang it, affix your hooks to the designated area of the fence.
Hang the star on the end hook with your lights trailing to the other hooks on your fence.
Use a planter or extra decorations to hide in front of your solar panel which will sit on the floor below your star.
