Pop the batteries in the battery pack and grab your glass vase/planter/jar.
In a circular motion, drop a few fairy lights into your vase. Place a few of your chosen decoration in the vase, taking care to wrap the fairy lights around them. You don't have to be very precise when doing this – it doesn't need to be perfect.
Repeat the fairy light/decoration stacking until you're near the top of the vase. Turn on the fairy lights at the battery pack before reaching the top. Don't worry about burning yourself – lights these days don't overheat so you can touch them safely.
Once the lights are on, it's time to hide your battery pack among your ornaments. Place the battery in the middle and carefully place the decorations around it, covering it as much as possible. Finish by topping up the vase with any extra lights or decoration. If you like, you can add a ribbon as the final touch! You can also switch out ornaments for pinecones or any other form of decoration.
Now it's time to place your twinkling lights in your preferred spot. Place them in a festoon window, on the dining table, on the mantle, in the bathroom or wherever you'd like to add a little Christmas spirit.
