Thanks for all the candid comments on this question!
For those that notice the difference ... or don't notice the difference ........ I wonder if that's somewhat determined by the fabric (weight, thickness, # threads per inch), different threads, the pattern, and perhaps other things?
And too, we each have a different ability to notice slight differences in results. Some will and some won't!
Will I change my ways as a result of this discussion?
I don't know!!!
However, I will be giving it a try this next while and see if I notice anything different.
(that is if I can remember to do it ... old habits die hard!!! :))
