I have heard people say that an installation looked like it was done by a blind man, well my stepson is blind. When I went over to the birthday party, he was telling me about the poor carpet installation that was done upstairs where he just moved. He said it was cut short in some places and not tucked in good in others. (he worked for me for a number of years). He could tell and he was right, that it was a bad installation and he is totally blind. I know the installer, he can do better work, I guess he just doesn't care. There seems to be a lot of that going around.
