What jwmcclin said!
Nutmegs have been widely distributed in whole form as a culinary spice for centuries and have entered the magical traditions of many cultures. In African American Southern hoodoo, the nutmeg is a fabulous gambling charm, but not notably used for love. Read the posts above your in this thread and click the links for more information.
If we were to bind two roots together for a love charm, we would bind two Blood Roots, or two Adam and Eve Roots (this is not an endangered species and not in commerce except by fraudulent dealers who substitute uselessly different items), or a John the Conqueror Root (male) plus a Queen Elizabeth Root (female), or two High Johns (gay male) or two Queen Elizabeths (lesbian).
We would probably not wrap the roots together with "cord." That term has special meaning in Wicca and other Neo-Pagan religions, but not in Christian hoodoo. We are pretty practical and would say, wrap it with thread or string. And we might specify red thread or red pearl cotton or red embroidery floss. We might embed the roots in wax before wrapping it.
We would probably fold and then tie the finished charm in red flannel, not in a paper envelope. A white handkerchief might also be used, again folded and tied, often tied crosstownways (corner to corner). Or we might put the charm in a red flannel drawstring mojo bag.
Hope that helped you!
