When sewing your pieces and seams, make sure you are sewing 1/4" only. If you're not, it will throw the entire quilt wonky. I use a shishka-bob stick to help guide the fabric thru the foot and match all the seams. My king size quilt came out even on all 4 sides! The long-arm quilter was impressed. Sew the side borders first then the top and bottom. I don't bother measuring for borders. I just sew and cut off the excess. It's worked so far - knock on wood. Good Luck
