I've read that too. The procedure in the manual took me a minute or two to figure out (weird wording) but it seemed good and strong once I followed the directions.
I think somewhere here on QB, I saw something about some wartime uniforms being chain stitched.
Don't the little ones "stretch" the clothes enough that the seems would pull at the stitches? I don't know that clothes around here ever lasted long enough to be let out.
I'm sure I've seen something here chain stitched, not just bags of rice either.
Now I'm going to have to try to figure out what it was. Like the DH doesn't think I'm weird enough already, now he's going to find me snooping in clothes...
