First gather these materials
Next cut three lines on each side of the triangle from the folded edge, making sure not to cut through the other side. The cut lines should be parallel on each side, leaving just a small space between them. You could always fold the triangle in half to make it easier and a little bit more even if the type of paper your using allows it.
Next unfold your triangle to make a diamond and roll the first two innermost paper lines together to form a tube. Tape the pieces together. You should see triangle shapes on each side of the roll.
Flip your diamond over. Take the next two paper lines and pull them together on the opposite side of the tube and tape together as before.
Keep doing this, alternating sides each time until all paper lines have been joined.
Repeat until you have 6 of these. Staple them together in threes
Then staple your two pieces together in the center
along with the 6 edges where each piece meets
Such a fun project to do with the kiddos
