The shifting issue might not be so bad if you sew one row in one direction, and the next row sew back the other way. I do this when I'm piecing long strips and it seems to help things stay more even.
I stitched it up one row and down the other, but with six layers over 42 inches square, I got about a 2 inch shift. If yours doesn't shift as much, great, just something to plan for 'just in case" :)
The lesson basically is this: Don't put your design all the way to the edge, give yourself some wiggle room!
