Using this cutter is very simple:

Roll out the modeling clay into a thin sheet, cut out with the cutter. Thin the round edges with a round rib or a smooth roller. Brush the center of the cut-out shape along its entire length with edible adhesive and fold, smooth, and stick it. Apply adhesive to the bottom edge of the folded clay. Slowly roll the clay, shaping the petals. This will create a small peony flower. For large flowers, attach another strip of cut-out clay.

With this cutter, you can create peonies in sizes 3cm and 7cm
