I saw this scarf at Staci's blog yesterday and finished it today! It's that easy. You can get the directions from Staci's blog, but I did change a couple of things that made it easier for me.
I used two skeins of yarn--almost all of it--following Staci's directions to make 100 pieces of 8 ft long yarn. Since I wanted to mix the two colors, I just pulled from each of the skeins at the same time to get the 8 foot pieces. That made it a lot faster to cut all those long strings--half the time.
Staci mentioned another blogger who made an infinity version of a braided scarf. That blogger, whose name I've forgotten (sorry, but you can hit the link and find it yourself;-}) tied pieces of yarn down the length of the three pieces to be braided to keep them from getting tangled. That made the process sooo much easier.
The only thing I might change the next time is that I might try braiding it just a bit tighter. I did it kind of loose because I tend to make things too tight when working with yarn. If you make one, experiment with this aspect a few different ways when you start braiding to see what you like.
I could not believe how quick and easy this was! From start to finish it was only about an hour. It's a nice quick holiday gift especially if you have yarn in the house.
