I make it a habit to quickly check remnant bins and dollar fabric bolts at Walmart whenever I shop. That is where I found this light purple/pink gauzy fabric for $1.50/yard.
I quickly grabbed 1 1/2 yards and the scarf was already halfway done!
Then tie knots at the end of each fringe piece.
Wear it a handful of different ways. You can sew the edges if you are worried about the unfinished edges, but I didn't. It bunches together anyway. Any fraying, which is minimal, just adds to the gauzy look.
It makes my plain Jane T-shirt and jeans look just a little more put together.
*This works nicely for any lightweight fabric. Just browse through clearance fabrics for the best deals. Really thin jersey knits work wonderful too.
