Years ago I got this terrific, funky teal yarn with flecks of pink and blue in it (it was the 80's!), and set out to knit a sweater that had these cool batwing sleeves. By the time I was done, the sweater literally stretched from end to end of my parent's massive coffee table with the cuffs hanging over the edge. And THAT'S the day I learned about gauge! That is the first and only sweater that I've ever completely finished, then completely unraveled.
I learned to knit in 1980. I made a batwing sweater, out of bright orange yarn! I never wore it, it was too bright. I'm sure, it had some lousy finishing on it, but oh well. After that experience, I crocheted most of my sweaters, and knitted small items, like purses and blankets for my dog.
Ahh. The 80s. I have some "kimono style" shirts today. They're really a close cousin of the batwing sleeves!
