Begin by making a template out of a bag. Fold the bag in half lengthwise and cut the tip to the desired shape. Also cut little notches or patterns into the long sides of the bag. Be careful not to cut too far into the centre.
If you want space for a light source (note: battery-operated LED) in the middle of the star, then cut a notch in the bottom of the bag.
Cut 7 to 11 more bags based on the template. Fold up all the bags.
Apply glue from the base to the point of one bag. Place the next bag on top and press. Repeat until all the bags are glued in place.
Open up the entire bundle like a round fan and secure with paper clips. When Christmas is over, simply fold the star back up again.
A star is shining! With paper bags, it's easy to make your own paper stars. Using this technique, you can easily make stylish paper stars for decorating your window at Advent. How to make your own paper star: Use between 8 to 12 bags, depending on how dense you want the star to be. You can test as you go while making the template to make sure you have the shape you want before cutting out all of the bags. Unfold the bag and check to see that you're happy with the results. Once you've cut all the bags based on the template, glue them together. Cut with patterned scissors if you want to vary the look of the edges of the stars.
NOTE: Use a battery-operated LED bulb if you want a light source in the star. Never leave the star unattended when a light source is in use.
