Yep it's a labor of love, it makes me and do love all of yous. lol
Oooh okay. Yeah I'm not sure how to explain what I did differently to get it to stay. Other than share how I was able to do it.
I placed 3 separate wall pieces. Place the Horizontal Clapboard in the middle, left and right corner pieces on the single walls. Recolor and retexture with wood. And then copy them to the house very carefully.

- Then look back over to make sure you didn't miss any corner spots *Blush*


And we do want the corner pieces as like you said, they are very essential to the look of the house!!
You do want to leave some of the decorating to your architect Sim. Though, you could add some basics for now?
I'll check over the TII Listing and make sure everything is good to go and ask if TeaTalker wants to download it.

Edited to add....
With us sharing photos back and forth I did see a few siding pieces I missed. *Blush* They've since been replaced. So thanks to our testing. The siding is staying put as well as the sides.
