It seems like a trivial difference, but due to the shape, the Infinity fold works best with square scarves whereas the DIY version can be pulled off on thicker longer scarves. Also, because of the different starting shapes, the way the scarves drape are also slightly different. I wanted to include both in case people had trouble with the Infinity fold on their scarves, but due to the speed of the video, the first step was a bit harder to convey :(.
