Robin sent a link to this fabric, which looks an awful lot like the fabric in that Which means she made the whole thing, most likely, and didn't alter it. That makes the green fabric an even more interesting and exciting choice!
It is soooooo geeky that I find this fascinating, isn't it? This is the dress equivalent of "and it was 10.3.9, not 10.3.8!". Or something equally geeky. When I start obsessing over whether someone used seam binding or did a turned-up hem, that's when you can start writing "*cough*, Erin …" in the comments. Okay?
