Sadly I was never able to perfectly recreate that cashmere sweater, though I came close. Getting perfect gauge is really hard to do on fitted garments for knitting. Mom had wanted me to learn to knit since I was really little but it never caught my interest until I was an adult. Through the pandemic we did work together to knit a modular blanket and sewed it together once we could meet up in person again! https://imgur.com/a/u4M4ynb
Fella is an English slang term for a man. Which is why they clarify even non-fellas (women/nonbinary) can still contribute. Hope that explanation helps!
