hehe ... no poetry
That looks strange to me. I'd be tempted to think "remelt" but I wouldn't panic unless I heard that from Galen. Maybe it got hung up on the rollers? From what I understand, the term "Diaper Fold" has fallen out of vogue. I still like the term but I don't see one there. A marble would need a single fairly neat seam for me to want to call it a Diaper Fold. And a nice smooth looping action visible from the side.
