12-inch-long pipe cleaners
To create the flower shape, fold pipe cleaner in half, and starting at the fold, create three zigzags on one side, each about the width of your thumb. Repeat on the opposite side, and then pull ends together to form a flower shape. Bend the ends down and overlap so they interlock. Twist together and flatten ends to the bottom.
To create the ring and "the flower's center," choose another pipe cleaner, and leaving about 1 1/2 inches on the end, crisscross the pipe cleaner between all "the petals." With the leftover pipe cleaner, create a loop around your finger.
Twist to hold in place, trimming excess with scissors, if necessary. The edges can be sharp, so after cutting use pliers to turn them in.
