We're doing M&Ms as our favors (I'm Meredith and FI is Matt, hence the M&M) and ordering them from the M&M website in our wedding colors. We're going to put them in a small 3'x4' organza bag for each guest at their place setting. My question is, for anyone that's done this before, do you have any idea how much I should get for a wedding of 150 people? They come in 5 lb bags and I was hoping to get away with one bag of each color. If it comes down to it, I'll just go out and buy some regular M&Ms, weigh one bag's worth and do the math...but thought it couldn't hurt to ask!
