"I bought this invitation for my upcoming winter wedding. I adore the way it turned out. I did the dark with lighter writing and payed the little extra to get the shimmer added which gives it that little extra something. :) Also, the size of the cards is more for postage...I ran into 20 cents more per invite..not too bad really."
