A few options I really like are:
I definitely like pink lettering and love the beautiful cursive typography of the first three. I thought I was definitely going to buy lettering that was cursive until I saw the ultra sleek and modern fourth option that grabbed my attention. Now i'm stuck.
Also warning- if you go to option 1's website, Lindsay Letters, you will become obsessed. She has the cutest stamps, stationery, letters, invitations....in the best fonts/colors! The whole website is adorable.
