This is in response to Ms. R's query! I hope it helps:)
First off, there needs to be two bends on this piece. Straight across from where the blue siding ends on each side. (I purposefully did NOT make a crease line, because I didn't like the look of a black line through the fish scale siding, but it's kind of a necessary step!) And another bend on the top line of the white siding.
The second error I made is this: there should be a crease line like so: (I penciled it in).
Then bend it under.
And this is how they fit together:
Once it's all glued together, it covers up that would-be gap very nicely. So sorry for the discrepancies! Hopefully sooner than later, my goal is to make an instructional video for the entire house. Thanks so much for visiting my blog!
