You will need to cut the paper into 1 inch strips.
If you have a paper cutter handed it makes this step really easy. However, not many of us have a paper cutter handed so here is what you need to do:
Use your ruler to make a mark every inch with your pencil. Once you have the top marked then draw a line down the paper to cut on.
Use your scissors to cut the strips.
Once they are cut you will need to fold the paper strips ion half to make a V shape.
