Materials: 1  3x5 index card, scissors

Directions: Fold the index card in half lengthwise. Make two cuts, one on each end, starting from the folded edge. Don’t cut all the way up to the top. Make sure to leave some at the edges still intact.
Next, make alternating cuts, spacing each around 1/8 to 1/4 inch apart. For example, for the second cut you would turn the paper over and cut from the non-folded side down to the fold. Then turn over again and cut from the folded side to the non-folded side. Go back and forth like this until you have reached the last cut that you originally made. Remember to not cut all the way to the end or the chain will fall apart.Next, you will slide the scissor into the “loops” that you have made on the folded side. You will not be cutting the first or last loop so leave those out.
