6. Lampposts That Glow Through the Glass
Lighting is everything in this build, and lampposts are the easiest win. I used dark oak fences with a lantern on top, spaced about six blocks apart along the paths, and the warm light spills across the snow in the best way. From outside the dome, you can see the glow through the glass, which is exactly the snow globe effect you want. I tried sea lanterns first and they were too cold and blue — stick with regular lanterns for that cozy, golden feel.
