hi, i'm almost done building my barn type shed with gamble roof and i was having a hard time installing the siding. using 16"x16' sections of TruWood siding. i have a over hang in the front and the 2x4's are at angles (3 of them, one on each corner of the roof) and i was wondering how i would calculate to fit somewhat snugly around them so it looks nice. i tried taking all kinds of measurements and transferring them to the siding but i can't get it to come out nice.

any help would be great. thank you
