I have many patterns that are quite old (I mean 1960s) and would like to know if there is a conversion chart from old yarns such as Columbia-Minerva, Spinnerin, Wintuk, etc. to newer yarns so I may still use some of these patterns. Haven’t knitted in years but am now retired an enjoying again this wonderful hobby. Thank you for your help.
Yarn conversion
Here’s a site that has charts for vintage yarns; they’re classed as light, medium and heavy and give the yardage. That way you can sub a similar weight and will know how much it needs of the old ones you have.
