I heard this to and do it to every piece of fabric I wash, not sure why it works but it really does and also I can tell if a fabric has been washed or not...
triangles cut away from corners = washed
uncut corners = unwashed
When I tell people I do this they look at me like I have two heads, but it really does work.
