Hello ladies!When my sister got married, she had me (as MOH) pass out envelopes with tips prior to the wedding.I was planning to do the same, but was unsure of whether I want to tip some vendors until I have actually received their services. I would hate to tip my DJ to find out they suck!Did you tip before or after the wedding? FI was thinking we should write thank you cards to everyone after the wedding and include the tip then, but I have never heard of doing this,Thank you for your help!
