I just hoop my quilt, load my design into the machine and start quilting. I recently got the "Edge to Edge Quilting on Your Embroidery Machine", by Amelie Scott Designs, and I like her method. She uses double-sided basting tape on the back of her inner hoop, and this really helps to keep the area of the quilt where you want it. When I did a different design, I just hooped it and tried to keep it straight, but it always went off-kilter for me. This method makes it much more accurate.
