Sasha!! I LOVE wall molding, esp white molding on BRIGHT colors (like you posted) I had envisioned it in my parlor, but time and money came into play, I reworked my design and I'm pretty happy with what I came up with.
I did do crown molding in the studio that I'm pretty happy with


But the space is too small and the color is too confining to do wall molding. Damn!
The key to home improvement is to set a reasonable budget, something just under what you can afford, then spent a metric SHIT TON of time researching cheap but effective materials, work, and ways to make your design work on your dime.
The left over, you'll find, won't be left over at all because you'll end up going slightly over your original budget (shit happens on a construction sight).
I also suggest exclusively dating handy men. For example, I dated a plumber and got TWO new bathrooms!
In the case of my CURRENT project, I couldn't have done this without Zoomie, as my budget was so. fucking. limited. Detroit and my two best friends have been amazing, too.
