Asking bridesmaids during covid

I purchased customized puzzles that asked if they would be my bridesmaid. You could always send one part of the proposal box first (the part that specifically asks them to be a bridesmaid), and then send the rest of the items later after they accept. That way, there isn't any pressure and they'll still eventually get the items.

My best friend just mailed each of us our bridesmaid proposal box

I reached out to mine and kinda asked first just to make sure that they were okay with it. Being a bridesmaid is a lot of responsibility and some people aren't up to it. I would suggest reaching out and making sure that they are interested in doing it that way you don't spend money on boxes just to get told no.

I just talked to each of them about it and skipped the proposal boxes.

I talked to each girl on the phone first to confirm they were okay (financially, schedule-wise, etc.) then I sent formal proposal boxes in the mail.
