No Quilt Police, most of the time if hit that situation just listen thru, thank for the info and figure no one dies if my project works for me it's good enough.
Do a lot w/ strips generally cut selvage to selvage, have ended up with other direction, No one died.
Have cut not w/grain a little off for me less fraying, No one died.
Don't generally use foundation, unless paper piecing or applique, even if didn't, No one died.
Don't always use 1/4 inch seams, No one died.
Are you catching a theme here...:)
If you enjoy the way you work, and since we are all a work in progress ( or at least i am).
Many patterns can be used with some strip usage, don't care for little squares. and can do much with the method.
Good Luck and Happy Quilting !! :)
