"So maybe you’re stressing over the fact that you need the blanket to turn out perfectly, and you don’t want to make more than one trip to the craft store... It isn’t as easy as “This much yarn for x,” because it all depends on the quality of the yarn you use and inches per stitch. "
"Yarn is sold by weight, not by length. The quality of the yarn is so important because it determines the weight. The heavier the yarn, the less you need."
"It is yarn made from wool that is fine and smooth. Worsted yarn is thicker than athletic attire and socks, but thinner than bulky yarn. This makes it ideal for making sweaters, hats, and, of course, blankets!"
"Inches of yarn per stitch are not set in stone. Depending on your own level of experience, skill, and even technique used, it will range."
"This is where the math comes in, guys. Count the number of stitches in between the pins, and divide that number by four. This is the gauge of your stitches, or how many stitches per inch."
