Step-by-Step Guide

1. Position the bed in the center-back against the right wall, with the curved wooden headboard touching the right back brick wall. Ensure the foot faces the front-left corner and the headboard's carved green swirl faces the small round window. The bed should align parallel to the floor planks, resting on the round rug's edge.
2. Center the round green rug beneath the bed. It should cover the lower two-thirds, with a visible green border on the front and right sides. Align the floral pattern toward the front-left corner, allowing bed legs to rest on the rug.
3. Arrange the pillows, blanket, and bolster on the bed. Fold the striped red blanket with stripes running front-to-back, then tuck a pale yellow folded blanket beneath it. Add a round blue pillow at the top center and a beige heart-shaped pillow slightly offset to the left.
4. Place the archer's quiver and boots at the foot and left of the bed. Stand a leather quiver with arrows at the bed's right-foot corner, and position a pair of short brown boots beside the left side near the dresser area.
5. Install the left wall shelving, potion bottles, and coat hooks. Position a horizontal shelf about two-thirds up, placing three potion bottles and books on it. Below, add coat hooks with a green cloak, yellow scarf, and hat. Place a lower dresser by the front-left wall with scrolls, a lamp, and books on top.
6. Position the front-left mat and treasure pile on the floor. The pale-blue mat should be flush with the floor edge, and above it, arrange an open treasure bag spilling coins, pearls, a jeweled goblet, and a tiny blue pouch.
7. Add the right stump table, candles, scrolls, and mushrooms. Place the carved stump table near the right wall with candles, a parchment, and a small pot on top. Set a wooden chair in front-left, facing the stump, and a cluster of mushrooms at its base.
8. Install wall windows, sconces, upper shelves, picture, round mirror, and vines with a nest. Place tall windows on the back-left wall and a small window on the right. Mount sconces flanking the arched window and an upper shelf with a small chest and books. Drape vines on the top wall edge, centering a bird's nest.
9. Add final touches: a small round mirror on the right wall, a framed starry landscape, and adjust lighting. Place a trinket box on the upper shelf, ensuring the dresser's drawer handle faces the front. Correct overlaps for a cohesive scene.
