I have the same issue. Not much problem on the back, but an issue on the front. They are softer & easier to apply if they are warm. You can try using a blow dryer to make them more pliable. They usually supply some short 2" pieces. Can you use those in the front? If you can, cut up one or more of the long clamps into small pieces. I cut mine down to 1", although I sometimes still just pin the front.
