Fold the sheet of paper in half. Mark well the fold with your hands. Cut the paper strip lengthwise, you should have 4 strips of the same size.
Separate the strips of paper. Start by making small folds in one of the strips, you should do the same with the rest but each strip must have larger folds than the previous one.
Make a cut along the base without cutting completely, turn the scissors and continue cutting in a semi circle. Do the same with the rest of the folded paper strips.
