Yarn weights in the United Kingdom are different to the United States which can be a little confusing now patterns are freely available online! I thought it would be incredibly useful to write a little conversion table for yarn weights which can be referred to again and again.
If you are substituting yarns, it’s always best to do a tension swatch before knitting up that hand-dyed cashmere just to be sure you have substituted correctly!
