Ah - that makes sense.

I was thinking of hand-knit clothing, which (as you say) tends to be big enough and chunky enough that you can see the stitches.

TIL - thanks :)

You can take a magnifying glass to any old t-shirt you have around. Or these days, you can also just take a snapshot with your smartphone and zoom in.

Compare with what you see on jeans and dress shirts, polo shirts, dress pants, socks, etc. It's quite interesting.
