Every one is in such a rush these days and everything has to be done fast. It is hard to convince people that the time spent prepping fabric, just like painting, takes a few extra minutes and makes a tremendous difference in the finished piece and in the ease of working with fabric that has less fraying and stretching.
These prepping methods are rarely taught anymore and it is a sad thing. As long as you are happy with your results there is no perfect way to get something done.
I am not a perfectionist but I do take my time and enjoy the doing.
