A:  I had to look elsewhere to find this information and it astounds me why so many states that sell dies and embossing folders do not give the dimensions. This is what I found: The finished envelope measures approximately 5.5" x 6.375" open, or 2.875" x 3.875" folded. In other words when you’re done making it it is approximately 2.9 x 3.9” in size. I guess the flat dimension is given so you know the paper size you need Answer provided by:  Brenda (6/10/2021)
