I knitted my mom a scarf for Christmas. It took a lot of effort to finish up this beauty. I got the cable pattern from a book called "Encyclopedia of Knitting" by Donna Kooler, but I'm prety sure you could find the cable pattern somewhere online too. I just added five knit stiches to the beginning and end of every row. The scarf measures 53" in length.
and here's the detail of the cable
Great story about the yarn. It's supersaver yarn by Red Heart. I got the Medium Thyme color about a year and a half ago and finally used it. Well, I only had one skein of it. So I went over to Joann's to go buy another. Turns out it's a discontinued color there. I had to use "sportweight" of the same color and brand of yarn in order to finish the scarf. I kind of doubt my mom will tell the difference, but I can! I guess I learned the lesson of making sure you have enough yarn before starting a monster project.
