First, Paint the tube green now squeeze the sides together at the top to make creases. Cut along the creases, to about halfway down the tube. Make two more cuts, opposite each other, halfway between the ones you’ve just made. You will have 4 evenly spaced cuts.
To make the stems, cut down the tube just to the right of one of your original 4 cuts. Do the same to the right of the 3rd and 4th cuts, so you end up with four thinner strips and 4 wider bits in between.
Bend these wider pieces out and cut them into long, leafy triangle shapes. For the flowers, place the 3 colored tissue paper sheets on top of each other and cut a strip. Cut the strip into square shapes, Rub some glue stick at the top of a stem and stick the middle of a tissue paper square to it.
Keep adding the squares, turning every time and pressing firmly in the middle to make sure they stick. Do the same for the other three flowers.
Once the glue has dried, get hold of the middle two pieces with your fingertips and give them a gentle squeeze and then give the whole flower a squeeze, all the way around, to shape it. Bend the leaves into place, bending the tips down.
