I've also been on a mission to include some of my own 'marks' rather than always relying on rubber stamps.
Well, I've found that I'm quite happy doodling on brusho backgrounds! They have so much texture anyway that adding a few pencil marks is quite therapeutic.
I made a pile of brusho backgrounds, chose some to add to my journal, packed a little bag of scraps of brusho background paper, scissors, a pencil, a fineline pen, a white pen, a pritt stick and a couple of coloured pencils and was able to transport my art journaling to different parts of the house and beyond!!
