@ryivhnn I had to use some small brushes and a very steady hand!

Yeah I use an 'artist's tape' or 'draftsmen tape' it's better than normal masking tape, because masking tape can tear the paper. If you go to a good art shop and ask for 'artist tape' they should have a few options. The most satisfying thing is pulling it off at the end to reveal a nice clean white border :) I put it on before I left the house.

Thank you for the comment!
