Right, for most patterns cutting is essential. But when I make things like napkins, placemats, tablecloths, and even a skort that I have made for dd#1 I have ripped because the pieces are just rectangles.
for anything that's gonna be a single layer rectangular, I rip. If the grain is really funky, or the design doesn't match the grain properly or it will be fused to a backing first, I cut with my rotary cutter and straight edge.
Of course, I lurve ripping fabric, it's one of my favorite things ever
Like the PP I rip after I wash to get a good straight of grain but after that I usually use my rotary cutter and a ruler to cut my quilt pieces until I see that my fabric is getting way off grain, then I rip a small piece to even it up again and go back to the rotary cutter.
