Measure wall height at multiple points and snap level lines before adhesive ever leaves the liner. Dry-fit the first row, confirm door clearance, and scribe tricky edges. Then commit, keeping reveals consistent so sunlight rakes across surfaces cleanly rather than exposing irregularities.
Switch plates, thermostats, and corner returns can sabotage flow if ignored. Use low-profile extenders, trim rings, and pre-mitered caps to absorb irregularities, and maintain continuity of grooves or ribs so the eye reads one calm surface instead of scattered interruptions competing for attention.
Chevron, slat, or micro-fluted motifs elongate sightlines when scaled properly. Keep segments slim near doors and heavier near focal walls to balance weight. Mirrored panels or satin finishes opposite windows stretch light further, creating the gentle illusion of volume without stealing any usable area.
