Expirmenting with coloured maps and borders

[TimetoDraw]

Hello!

Here's my first fully coloured map WIP. It's a continent view of my smaller Jura map.

What are your methods for creating borderart? Do you pen tool it? Freehand it with painstakingly steady hands? They seem to be an art unto themselves and not something I've attempted yet. Though this map would benefit from a border.
