Today I got kinda sidetracked - which is par for the course! I have a folder on my computer called "To Be Sorted", I came across a picture and the window in the picture caught my eye.
This one will fit on an A6 card. The ones below are half A5 size which is 74 x 210 mm or 2.9 x 8.3 inches. I actually thought DL size was half A5, but when I googled it, it wasn't.
