Squaring up a panel sometimes is not an option, you might be cutting into the pattern. I have made several quilts from panels and I add borders until it's the size I want it. One thing to keep in mind. Most panels are longer than wider so I add more yardage to my width of the quilt than the length. If that bothers you then I would suggest you stay clear of panels.
