Brush Strokes, Butterfly, and Speckles

Sometimes previous ceramic work crops up and I can't recall how I actually made it. Today I was enamored with the organic look of this plate. Did I use a stain or a glaze filled toothbrush to get the black speckles? Did I use a stencil for the butterfly? I see some faint brush strokes in there. And what do you know there's a napkin ring too. Food for thought.
