Cutting a 12 x 12 sheet of cardstock will give you a totally different look and measurement for your card base.
First, align a 12 x 12 sheet of cardstock (NEW Kiwi Kiss shown)at the 6" mark. Cut.
Here is the result of the first cut.
Next, align one of the pieces of cardstock horizontally at the 6" mark again. Cut again.
This is the result of the second cut.
Then, align a piece of cardstock at the 3" mark. Score.
