I like this as a start; however, to me it feels too narrow to be a proper border.
This feels right to me.
I like it but it feels a bit weak.
This works. I'm wondering if there isn't a little too much red?
This works too.
For more border ideas go to My Posts by Subject in the sidebar on the right and click on Borders.
