T.K.
If you are all going in together and everyone contributing on one gift to be presented by the group, I would put cash in a card. Theres nothing like the look on someones face when they open an envelope full of cash. No reason for one person to deposit the money and then write a check. Plus it makes it all too obvious who the organizer was. That's poor taste imo. But, as in the case of my kids coaches, we usually just give our own individual card with a gift card in it. It's too difficult to organize a group of parents.
