The powers who many quilters give power over them is flexing their muscles again. For years its been use only 1/4 inch seam allowance. People got bored and declared you should now use a scant 1/4 seam allowance. God gave you freedom of choice, don't let humans take that away from you on something as personal as quilting. I'm thinking, except for precut kits, you can adjust a seam allowance as you see fit.
