I really love scarves. They are probably one of my favorite accessories. I have a lot of scarf so rather than go out and purchase a circle scarf, I'm making due with what I have.
I took a wide and long scarf (2 ft x 6 ft) from my closet and tied it in a double knot at the end. When I tied the double knot, I didn't include the entire width of the scarf-- that would make the knot too bulky and attract attention in the back. I simply used part of each end and tied a small knot. Wrap around your head a few times (in my case, three times was a charm).
Easy, right? I know!!
And now your kids and dogs will love you so much more. At least mine did.
