Look at me getting ahead of myself. Here is a concept drawing for my plan. (Okay, "concept drawing" might be a bit of a stretch.)
Phase 1: Paint trellis
Phase 2: Paint white below trellis
Phase 3: Paint gray above trellis (and the adjoining wall to the left)
Phase 4: Install chair rail
Phase 5: Make and hang hook rack
Last night I finished phase 1. It took a week of painting (stretched over a month), but I finally finished it.
Remind me to show you what brushes I used to paint it sometime. (Hint: they were tiny.)
