I was told by a few longarmers that I was very brave in attempting to crosshatch such a large area. I was successful although I'm not sure I'd attempt it again. It was definitely a lot of work and took lots of time and care to get it right.
I also stitched around each and every motif on the quilt, from the littlest of leaves to berries. Chevrons were added in blank areas of one border to draw the eye around the quilt and in some areas I quilted ghost branches/leaves. Piano keys were placed in the 2 busiest borders about 1" apart.
Enjoy.
