Year – 1970s
Size – 34 to 44 inch bust
Yarn Size – Emu Fiord, which was worsted or 10 ply according to Ravelry (though I don’t think either term was used in the UK). As I’m going to say a lot on this website, my local yarn shop has advised me that in the past, chunkier yarns weren’t as chunky as they are now. Ask your local yarn shop for advice or swatch your projects to achieve the correct tension with the yarn you want to use, otherwise the sizing will be off.
I had a sweater just the same I knitted it in 80 been knitting since my memom took me to the yarn store with her by the hand 5ish
