What are you most proud of? Finally getting the corners boxed accurately, they're just hard to line up! What advice would you give someone starting this project? When boxing corners, take extra care with lining seams up if you've used a thicker interfacing. When pinning, actually pull the seam open a bit with your fingers before sticking the pin in to make sure you've got it exactly in the crack of the seam. Otherwise, like mine did a few times, it won't line up at all!
