At the very end of last year, my third grade students cut apart plastic water bottles to make these flowers. I started them off by cutting the bottom of the bottle off, then they continued with scissors. You can round off the edges to make the petals look more realistic. Then, these were painted with acrylic paint. I hot glued these down to a large white piece of foam board. Some kindergarten students also made little round lumps of model magic and then poked wire, beads and chenille stems through the model magic. These were also glued to the final piece.
