Just right for this special occasion. Arrived in just a few days giving plenty of time for RSVPs. One small problem which was mine entirely. I forgot to put the time on the invitation cards. Had to print out a small note to go with every invitation card. Moral of story - don’t be in a hurry and don’t press ‘send’ before reading everything carefully. .
