Getting the exact yarn named in a pattern is rarely easy. It’s been discontinued, imports have stopped, or it blows the budget. So most knitters substitute. The problem: that knowledge is scattered across social media, forums, and blogs.
The first things to check in a substitute are weight and gauge. Even two worsted yarns differ subtly between brands, so always knit a swatch.
Next comes the fiber’s character. Merino is soft but grows; cotton is sturdy but heavy. The key is to picture the silhouette the designer intended and choose a yarn with a similar personality.
There is no perfect substitute yarn. There is only the yarn that suits your hands and your project.
Finally — leave a review. Your experience using yarn B instead of yarn A is the most trustworthy information the next maker can get. That’s why we’re building this database.
