It is probably not a good idea to use cursive when addressing an envelope - no matter how great your penmanship is!
I am of the opinion - until “vote in person” is restored here - that signing a ballot in cursive is a serious mistake.
Signature stamp is high on my list (I regret that I have not done so sooner, as I’m sure that I have been disenfranchised due to my poor cursive and inconsistent signature, an excuse for the enemy).
