Ok, so i seem to be running into some problems finishing this Sopwith pup.
I am trying to make templates out of cardstock sheets, so that i can cut the correct patterns for the metal sheeting that covers the nose area.

However, I am getting a small "pucker" when i lay the template down. No matter which way you smooth it, there will be a small pucker up in 1 area or another. I am only bringing it down to the edge of the bottom meets the side, so i am not trying to wrap underneath.

Does anyone have any suggestions as to how i can solve this. ??

I will attach a photo which i think is causing the problem, but still i am at a loss for a solution.

Thanks all!
