Right now, it measures almost 71 x 71 with no borders. I can't decide if I want to add a skinny red border, then a green border or just go on and add the green border - I don't really need it much bigger, it's going to be a holiday table topper. I do want to put at least a one inch border on there to collect all those seams on the edge, it'll make it so much easier to bind.
Not many people have been opting to do sashing, but I'm glad I did!
