Frequently Asked Questions
Can I substitute cotton for wool?
Yes, but be mindful! Cotton lacks elasticity. Your fabric may drape more. Consider blending fibers or adjusting your pattern expectations.

What if my gauge is different from the standard?
This tool provides a starting point. Your personal tension and yarn brand affect gauge. Always knit a swatch, wash it, and measure to be sure.

How do I adjust for a different project size?
The calculator scales yardage linearly. If your pattern has multiple sizes, ensure you are using the yardage for your specific size from the pattern.
