I have not done an all-white quilt but have done a log-cabin in all neutrals that included white. I like the quilt but there's a temptation to throw in a "bit darker" color for contrast. Try to resist that urge...i had 90% creams and whites and then included a solid that was just too tan. the quilt is fine and all that but it missed the mark from what i really wanted. Point is--if you intend to do all white..then stick to that rule and try to find as much variety in prints and textures that you can.
