I did a little research (followed the etiquitte board back to the last thread about engagement parties) but my question is a tad different. We mashed our engagement party with july 4th. Because we didn't have enough money for everything (and our families have repeatedly offered to help with all manner of things even if it isin't wedding related) we had a potlock. I even made the cake. My question is...in this situation, I need to send out thank you notes?
