This is a close-up of the corner. You can see the inner hardanger border, the Algerian Eyelet stitches between the satin stitched rows, and one of the funky hearts that are in all four corners.
And here you can see what the hardanger section looks like with the threads removed, but before the remaining threads are wrapped and woven. The Algerian eyelets on the right side are only half done. The first half of the stitches is worked in one pass and the second half is worked on a second pass.
