Well, that all depends- I prefer a variety. Take for example when you have sewn several seams then suddenly realize one of them is laying in the opposite direction as the rest. My theory- once I've sewn the layers together-I'm the only one who knows exactly how many mistakes I made. Course if someone feels the need to inspect it and point them all out to me I obviously am speaking to someone who is so insecure they have to put someone elses work down to try and bring theirs up. With that aid- I'm sure their are those who would cringe at the thought of not doing it just so.
