Cut the two sheets of tissue paper in half width-wise. Stack and align the four pieces of tissue paper.
Accordion-fold the stack of tissue paper from long edge to long edge. Make the folds between 1- and 1-1/2-inches wide. You don't need to measure the width of the folds--just eyeball them.
Trim the ends of the folded tissue paper to make them rounded. Wrap the top of a green pipe cleaner around the center of the folded tissue paper to create a stem.
Fan out the layers of folded tissue paper to create a full blossom at the top of the pipe cleaner stem.
Cut a six-inch tall and two-inch-wide diamond shape from green tissue paper. Twist the diamond across the width to create two leaf shapes.
Wrap the pipe cleaner around the twisted center of the two leaves once so the leaves are about halfway down the length of the stem.
