I have EQ5, but to be honest I don't really like it.. probably because I never really learned to use it, and I've been quilting long enough that I just got used to drafting by hand.. I don't even use graph paper. I have a BIG sketch pad, and a variety of rulers, a compass, protractor, mechanical pencils and some string. I just mark a square the size I want my finished block and go from there...haven't had any problems to this point.
