Hi,

I want to try knitting the leg warmers from the following patterns found on this site:

Kids

Women

They only express the number of balls required for the pattern with specific brands of wool, but I was wondering if anyone would know or give me examples of how many grams and yards would be required using various types of yarn? I do have left over balls as follows, but not sure if it would be enough:

x3 50g (super fine 1 kroy socks 75 wool 25 nylon)

x1 100g (medium 4 pure wool)

x3 50g- 130yds 50% cotton -50% acrylic

As you get experienced, can you actually guess how many balls are required for patterns that are not clear how much you need based on the pattern? I know you can calculate based on the number of stitches or inches required, but math was never my strong point - would that make me a terrible knitter?

Thank you so much!!
