To me, a handwritten script is the perfect blend of fanciful script & messy handwriting. They have a slightly imperfect quality - a gap here, squiggle there - that gives them that 'messy' feel.
Some of my favourites - been using a few of these for years! War Letters is a newer find but I love it - need to find the perfect project for it. St Andrew's Queen is everywhere - pretty sure it (or something very similar) is on some bread packaging here in Canada! And Arsenale White has that perfect kid-like quality while still being readable.
Which is your favourite?
