I used about 145 yards of handspun yarn from the Etsy shop Marajane Creations with an average WPI of 18 wraps per inch, but a wide range of yarn weights could be used for this project. You may want to use a different size needle if your yarn is widely different from mine.

This pattern was on About.com (which no longer exists) and has been deleted from their site, but for now it can still be found on the Internet Archive. They redirect and delete pages a lot so you may want to download/print to save.
