The Infinity vs. DIY Infinity
The difference is very subtle – the first fold. The Infinity is folded along the diagonal while the DIY Infinity is folded in half, horizontally. The Infinity starts off as a triangle, whereas the DIY Infinity begins as a rectangle. 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.
