How Much Yarn Will You Need?
Many crocheters substitute yarns all the time but are unsure how to calculate it. Crocheters sometimes do not know the math formulations how much yarn they will need when substituting.
I have created a calculator to help crocheters figure out how much yarn they will need.
The calculator is designed to match the same weight class of yarn, using the same size hook. Changing hook sizes or weight classes for substitution requires samples and gauging to be done to figure that out. It’s not a theoretical calculation.
