<human>: How do I make a pom-pom for my Halloween costume?
<bot>: To make a pom-pom for your Halloween costume, you will need a large piece of fabric. Cut the fabric into strips that are about 1 inch wide and 4 to 5 inches long. Tie each end of the strips together with a knot or bow. Then, fold the strip in half and pull it through the loop. Continue this process until all the strips have been used up. Finally, tie off the ends of the strips to form the pom-pom.
