Trim about 1 in. off the top of the glassine bags. You can stack about 5 bags and cut them at the same time. Then, fill the bags with the Halloween candy.
Cut a piece of Color Duck Tape that's a little wider than the bag. Place the tape on top of the printable tags and then place the entire strip across the top of one of the bags filled with candy.
4. Fold the top of edge of the tape towards the back so it sticks to the back of the bag and seals it closed. Trim the left and right side of the tape with scissors. And, that's it! Repeat the steps above to make as many bags as you need.
