I think that the most important "secret" that ever came out is the rotary cutter, ruler and mat. I often will show someone a quilt I've done or working on and they'll say wow all those little pieces . Sometimes that might be true but usually it was something that was cut in mulitple layers at the same time. Sewn together, re-cut, turned or flipped and resewn. Rarely do I admit that I can do in just a couple hours what it took quilters 50 yrs ago days if not longer to do. Just let them be in wonder.
