Steve,
I was just going to say, way to go! Nice job! and all that but I think a little lecture is in line here!
Your quilt is lovely and you've come a long way from where you started. You are not, I repeat, NOT, to go around pointing out the minor errors on your quilt. Really! No one is going to notice them at all. I had no idea your center seam was a tad off! It just doesn't show up in the overall picture. Just smile and say, "Thank you!"
I subscribe to Eleanor Burns theory. She says to, "Hang it high and keep it moving!"
With each project we learn something new and improve our skills just a wee bit more. Looking forward to seeing what you come up with next.
