Unique wedding gift for guests

Favour my friend called that her immediate younger sister is wedding soon.
She said she was thinking about gifts for the guests, saying that i should suggest for her. I told her she is already on line of creativity that she should produce something out macrame for her sister's guest. She said she can't come up with any idea. I told her to give me few minutes let me think.
The thought of macrame keychain came in to mind. I called her and told her about it, she seemed not to grab it, until i sent her sample of what i meant
She followed my idea and achieved her goal.
