Here's the two things I learned about pocket doors:
One: kids love them. They are way more fun than normal doors.
Two: it's best to install them into a new wall or plan for them when your walls are open. Our contractor said it's much easier to install the kit and hardware before the trim and such goes on.
The other last-minute switcheroo I made was the sliding exterior door. The old door (which was 30 years old and original to the house) opened as a right-handed door. It always bugged me because it meant I could never put anything beneath the giant windows.
So, I chatted with Home Hardware and they helped me find a left-handed sliding door and I made the upgrade and it's just a small thing, but it's actually a big thing!
It means there's better flow in the room. I can now have a pretty little plant corner under the window and the new door has a much better seal on it, which means fewer cold draughts and such.
When people see this room, they almost always comment on the pops of colour! The colours only really work because they are bouncing off the white walls. For the white, I chose Beauti-Tone's Love Letters (WB002-0) and honestly, it's like the best white paint ever (And I've used a lot of white paints in my time as a DIY Blogger).
