I've not used mine nearly enough, but it looks like you perhaps traced the actual opening with a pencil? With a guide bushing, on a router (or rigged to hold a pencil), the tracing will be smaller than the pattern--and reduce or eliminate overlap. No bushing, you get what you drew. Bushing "17" you get their picture. Larger bushing will leave gaps between the petals. I did one a few years ago where i started with the picture in diagram, contrasting inlays (cherry??). Then used a larger bushing, offset--added smaller petals of the boxtop wood (white oak as i recall). Gave it to somebody before i thought to take a picture. It was cool--but i've not done that since.
