KnitWit 60: How much yarn? Part 2

Summary: Totally knitting episode. I talk about how to calculate how much yarn is needed to knit a sweater. It involves some work in that you will have to knit a swatch but you were going to do that anyway. Right? You will need access to a scale that weights very small amounts. I use a postal scale. Formula 1 : TA = C * L * 3 / 2 where: TA: total area of sweater C: circumference of the sweater L: length of the sweater In words, the approximation of the total area of sweater is the circumference of your sweater times the length of your sweater time 3/2. You need to relate the area to a weight. So weight the swatch and calculate the area of your swatch length* width Formula 2: SA = k ozs, SA: swatch area. Formula 3: Y = TA * k / SA where: Y: weight of yarn needed TA: total area of sweater k: weight of swatch SA: area of swatch Yarn needed in oz is total area times weight of swatch divided by area of swatch. I hope you find this information helpful and not overly technical.
