How to Use This Guide

Select the CYCA weight category of your original (pattern) yarn.
Enter the gauge and yardage from your pattern or swatch.
Select the CYCA weight of your desired substitute yarn.
Click Compare to see compatibility, stitch multiplier, and yardage conversion.
Always swatch with the substitute yarn to verify your actual gauge matches expectations.

Note: Fiber content (wool vs cotton vs acrylic) also affects drape, elasticity, and gauge. A wool DK and a cotton DK may behave very differently at the same CYCA weight.
