when I first started quilting, nothing and I mean nothing lined up....my blocks, my seams, etc....just learned this year I was using the wrong rotary cutter (for me that is). Now my cuts are better and I am no longer shaving my rulers....yes, shaving my rulers...anyway I kept plugging at it and improved over time...learned how to fudge this and that and never had a reciepient (sp) ever complain about a guilt or placemat that I gave them! Your work is beautiful and remember only God is perfect
