Simply said : Bugger

Parchmenting a birthday card for a friend when I noticed that the felt-tip pen I used to colour the leaves has left smudges. It's not that obvious, but to me it sticks out like a sore thumb, and I don't want to give a card that's not quite right.
You can't use an eraser on parchment, so maybe I'll throw a bit of glitter over it.
Must be more careful.
