I found this site by looking for a knitted scarf that tucks into itself. I once had this pattern and in a frenzy of cleaning threw it away. There are two patterns. Once has blunt edges and the other tapers. It is the tapering one that I am looking for, although I realize I can adjust the blunt edged one. Thanks!
I made one for my 6 yr old daughter last winter called a Keyhole scarf that tucks into itself. She love it! It uses the feather and fan pattern. It is about midway down the page.
