I make medium long soakers for my daughter. She doesn't need a large, but the medium wasn't quite high enough in the back. Here's how to alter the pattern to get a higher rise. Cut the patter in the size you like except don't stop at the waist that comes with that size. Instead, keep cutting upward along the side seam until you get to the line that goes with the next size up. Here are some pics for making a medium long.
