Hello! I am seeking to connect a rod to a metal flower petal but do not know what tools or method to use. Attached is a picture. The center of the petal is probably 15mm, maybe a bit smaller. It is iron but pretty light/malleable. Suggestions?

Thanks in advance of any responses. I am working on a project and do not have much experience in DIY, so I’m on a fun learning journey. Simple ask here I know…
