What does she mean by "cursive letter"?
Native speaker’s answer
Rebecca
By "cursive letter", she means the handwriting style she wrote the invitations in, which is called "cursive" because it looks like it curves a lot. "Letter" here refers to the alphabet characters! Ex: I tried to learn how to write cursive letters in school, but I could never do it properly. Ex: Oh wow! Your handwriting looks so nice! Is that cursive?
