If you have some thin paper (like rice paper) you can write a poem or something personal and enclose it with the flower petals.
Oops, just saw your 2nd paragraph. Yes, a drawing by you would be nice also. I think it's more meaningful when it's something from you.
There you have it: a beautiful locket, some dried rose petals, a drawing by you, and a sliver of nutmeg. All wrapped beautifully and cushioned in jewelers cotton.
Lucky lady.
