The football team my h2b supports have agreed to ask all the players to sign a letter for me to give to him on the morning of the wedding but have asked for me to send them over some wording. Has anyone had something similar who wouldn't mind sharing the types of thing that were in the letter? Don't want it to look blatantly obviously that it's been written me haha. Tia. X
