To start, fold your Neenah Crest Solar White 7 x 10 piece of cardstock in half, so that your cardstock is now 7 x 5. Place your die (Spellbinders) over the folded cardstock, being sure to let the edge of the die at the fold hang over the edge (otherwise, you will have 2 separate die cuts instead of a folded card).
Your end result should look like this~
Sometimes the die does not cut all the way through and you have to trim the shape by hand, or, as in this case, I opened up the card and die cut the bottom layer, being careful not to cut all the way to the folded edge so as to keep the card intact instead of cut into two pieces.
Now cut a single layer of the Neenah Crest Solar White cardstock from the same shape. You will use this shape to adhere on top of your folded card. This will cover up the unfinished folde edge.
I have not popped all of the pieces out of the die cut in this above example, but it is a complete die cut. Your end result will look like this~
