Autumn Panel

I finished quilting the Autumn panel and sewed the binding to the front but have not finished sewing it down on the back. I wanted to block it first because it did not appear perfectly square. I am not sure why I had a problem as I trimmed the panel all around and it was square and the 2 borders were square after they were sewn on. It is pretty densely quilted and maybe that is where the problem lies. I outline quilted all the leaves, maple seeds, tree limbs, the bird, and all the lines between the light rectangles and the dark background.  The veins on the leaves are quilted and the light rectangle areas are free motion quilted with echo quilting and some pebbles where they are distinct. All the dark area and the borders are quilted with straight parallel lines about 1/2 inch apart.

This is a photo of it up on my design wall. I pinned it and sprayed it with water until it was damp all over and then worked on pulling it square and flat. I reworked the upper and lower right  corners again after I shot this photo.
I am hoping for the best. I am pretty confident that it is going to hang flat. If it is not square the inner border will likely draw attention to that. At any rate, for better or for worse, it is going to hang right across from  my front door where it will be seen by all who enter.
