Recently I went to a wedding that was very non traditional. They were married on Halloween, all the bridesmades were dressed in black, each having a different dress. (which I thought was really smart, because I would think if they picked out the dress they would for sure wear it again.) I didn't want to make a normal all white card so decided since they had lots of black I would play off that.
Here is the card which I made the design on my eclips.
