I love to make quilts and I am very fast. I start out with one block and test the process and then figure out how to make it quicker and easier. I am organized and use a lot of chain piecing and paper piecing techniques. I am not going to change my way of doing it because someone else wants to go slow. I completely enjoy the whole process but I dont agonize over my decisions.
I once went to a needlework shop and had to stand around for 3 solid hours while a friend agonized over every decision. Never again. I have also spent hours and hours while long discussions of fabric went on. I drive myself now.
I remember one long arm teacher at the MQX show in Oregon. He went to his dealer and had his machine souped up to go almost 2X faster since he enjoyed working with a high speed machine and was very good with it. I would not dare tell him to slow down.
