So, I'm installing wainscoting in our nursery (baby girl coming in july), and I've run into an impass. I have two 135 degree corners that I am having a hell of a time figuring out how I am going to trim. I can't find anything like that online or at my lumber yard or home improvement store. Does anyone know of any good ways to fabricate such a trim piece out of other pieces that are readily available, or better yet, does anyone know where I can get such a piece? I tried taking a piece of 90 degree corner trim and getting it wet and widening out the angle, but that stuff is pretty tough and snapped when I tried to put any pressure on it. Any input would be great.
