Cut a piece of wrapping paper to 29-1/2 cm long by 20 cm wide.
Place the wrapping paper with the shorter edge in front of you.Make pencil marks on both long edges of the wrapping paper at the dimensions shown in the photo. First 5cm down from the top, then 2cm, 2cm, 11-1/2cm, 2cm and 2cm. There should be a 5 cm section left on the bottom.Important: the 11-1/2 cm section should fit the length of your toilet paper roll. Measure your paper roll and adjust the center measurement if necessary. The rest of the numbers can stay the same.
Use a ruler to make lines from one side of the paper to the other at each of the marks.
Step 3: Fold the paper
Fold the wrapping paper back at the first, second, and third lines.
Now fold the paper so the second line is sticking up (creating an upside-down 'V' if you look from the side).
Repeat these folds at the other end of the paper.
Step 4: Cut sections out of the paper
At one end of the paper, adjust the folds so there is a single fold at the middle line as shown in the photo. The 5cm and first 2cm section should be folded flat behind the paper.
Cut a series of triangles along the folded edge from the bottom to the top of the 2 cm section.Try to keep the triangles roughly the same size, but it's okay if they're not completely the same width.
Repeat these triangle cuts on the other end of the paper.
Step 5: Roll up the Christmas cracker
Add glue tape to both sides of the 11-1/2 cm section. Add more glue tape to the right side of both the 5 cm sections (above and below the triangle cuts).
Place the toilet paper roll at the left edge of the 11-1/2 cm section, pressing it onto the glue tape.
Roll up the paper roll until it meets the other side.Press down on the seam of the middle section, as well as the 5 cm sections, to make sure the glue tape is secure.
Step 6: Finish off the Christmas cracker
Apply glue tape to both ends of the cracker snap.
Insert the cracker snap into the Christmas cracker and through the paper roll. Press down on both ends to secure it to the rolled wrapping paper.
Cut two pieces of ribbon, each of them roughly 14 inches long.Tie one ribbon around one side of the cracker, in the middle of the section with the triangle cuts.
Fill your Christmas cracker with gifts, letting them slide down into the paper roll. If you need more room, shake the cracker to get them all the way down.(Asnowbank is the answer to the riddle in the picture below, by the way - haha.)
Tie the second piece of ribbon around the other side of the cracker, closing it off.
