I love watching Jenny because her enthusiasm is infectious, but her techniques aren't always optimum. She definitely irons rather than pressing. I could not get good results that way. I always set my seams first with a quick press, then press again with the seam going the right way.
I think it's just a difference in the style of quilter. She's more down and dirty and I put more importance on taking the time to learn the fundamentals. One way is not better than the other way; whichever way gives you more enjoyment is the right way.
