This wavey shaped card looks pretty cool standing up on the waves. The colour of the cut and fold card base will be visible through the "Happy Birthday" sentiment on the first of the three card top layers. The colour of the first layer is visible through the pearl string on the middle layer and through the sail and the birds on the top layer. Finally the colour of the middle layer is visible through the waves and the boats' hulls on the top layer. It may sound a little complicated, but trust me - it is very, very easy to see and to do right, when you open the cutting file. :) The insert has an upper part and an bottom part, which are to be pushed together with tape on the revers side. For my own card I cut the upper insert part in white for a hand written greeting. The bottom insert part is cut from the same cardstock as the card base as this will be visible as a part of the waves, both when the card is standing and when it is closed.
