In our May 18, 2023 studio update Lynn and Helen chat about Olive Knits' upcoming Lemon Spritz KAL, our Maryland Sheep and Wool colorways Golden Anniversary and May Morning, and what to think about when substituting yarn.
When thinking about what yarn to substitute Helen recommends starting by looking at the gauge of the suggested yarn (since that will be more representative than the gauge on the pattern,) then considering fiber content and construction characteristics. Lynn adds that if you want to start at the other end you can swatch to figure out your ideal gauge for the yarn before looking for a pattern. Then look for a pattern that will work at that gauge, keeping in mind the characteristics of your yarn.
