This card can be achieved using any nested dies. The largest square die I used was 4 5/8" x 4 5/8". If you are using a different size you will need to follow the following instructions to determine the size of your base cards.
1.Measure your die from cut line to cut line.
2.Double the measurement and add 1/8"
3.Make a mark on the halfway point on the long side of your base top and bottom.
4.ut out the largest die you are using and mark 1/2 way point top and bottom
5.Align the largest die cut on your base piece centrally where marked.
6.Mark where your side score lines should be - ( allow about 1/16"from the die cut piece)
