Aashley - I also needed to look those two words up! Glad to know I wasn't the only one confused/intrigued. :-)
Such a great conversation here and so many good thoughts on both sides. I'm a presser, personally, especially useful when I've pieced my bindings and I also machine my binding on the top then wrap around and hand sew on the back. Probably one of my favourite parts of making a quilt - not only does it mean it's almost finished, but I find it calming and extremely satisfying to watch it all come together in slow motion. :-) I think if I was going to use a thicker batting I'd be more inclined to try not pressing to see how it changes the fold.
