I just picked up the largest size of POCs VPD 2.0 DH knee pad. To my disappointment, the thighs are wayyyy too small, but I want to keep them.

So has anyone ever tried making knee pads or something similar larger at one opening? If so, how'd you do it and how'd it work?

I'm thinking I can just cut a wedge out along the entire length in the back and add some nice stretchy fabric to give me an extra 1-2 inches in circumference around the thigh without changing the calf (which fits perfect). What you think?
