Nursing Cover Part 2

I was asked to make a nursing cover for a new mom recently (the purple one pictured above). I haven't been happy with my old one so I was excited to try again and change some things. I found Sew Much Ado's tutorial and it was perfect and easy to follow. I decided it was about time for me to make myself a new cover too (the paisly one pictured above)! I unstitched my original and started from scratch. I love love love how they both turned out.

There was another tutorial I liked by Freshly Picked but the D-rings I had on hand were 1.5" and it calls for smaller ones but I had to mention this one because there's one thing she did that I tried to copy and couldn't. I have no idea how she pulled it off. Don't think I'm a dork for loving this tiny little detail so much but I tried over and over to do it like her and I finally got out my zipper foot and it still wasn't great so I gave up. Here's hers:

Cute right? Any idea how she got the stitch line so close to the rings??
