I am sure there is a faster way to cut your triangles from squares if that is what you are referring to....however because of accuracy I still do mine one at a time which will make some of the quilters here scream of boredom and other such things. For me stacking them to cut would require great patience in lining them up perfectly as to not distort the square. I just cut corner to corner and do not have any problems doing it the old tried and true way. It takes time but I am very happy with the outcome and have never had any problems. I am just one of those oddball quilters that enjoy the old ways.
Hopefully those quilters that use all the shortcut techniques will chime in here to help you as I know there are a lot faster ways to do things than I do.
Whatever you choose for yourself just enjoy the process and have a great time.
