This up-and-down flower is easy to do, since the petals are done continuously, not individually.
Divide 2 circles into 6 (the big one is roughly 3cm diameter, smaller one is 1cm diameter).Position the points as shown above. Make small stitches on the points.
Beginning from one base, bring the thread up and insert the thread into the stitches done, alternating up and down to form a six-petal flower.
Bring the needle up at the base of one of the petals and make buttonhole knots continuously to cover the 6 petals. If you ran out of thread, stop at the base, not tip and continue from the same point.
This flower is easy to embroider since you don’t have to make individual petals.
