Now, that I spend time happily writing the baby blanket patterns, I needed a way to give some estimate of how much yarn is needed. While usually, for me and for my friends, I just wave my hands in the air and say ‘just use what you have’, here I need to be more specific.
Since my charts are in chunks of 5 sts and 5 rows (as oppose to 8 base grids), here is the way I do it:
1. knit 25 sts. Undo and measure the length in yards or meters.
2. Count how many squares of 5×5 of that particular color/yarn are in the chart.
3. Multiply the length by the number of squares you need, and – voila! you have an estimate!
Hope this helps!
