Don't know if both our mom's were fibbers , but after catching a braid on a picket fence, the story sure made me pay attention.
I think it might have been a standard "if you keep doing that you'll go blind!" type of warning.
Don't get me wrong about the ironing, I'm a 98% "wash 'n wear" person too. I use it mostly for guests, the tablecloths. I have a bunch of old old, very worn-out linen napkins that I only use for me (due to the frayed edges). When they are finally all done in the laundry, I iron them all at once. Only other time I use it now-a-days is when I'm sewing - and I don't even sew very much anymore due to astigmatism with my eyes.
