Clipping printed photos onto string lights adds a meaningful touch to the celebration.

It makes the space feel personal and memorable — not just decorative.

8. Pillow Cover Swaps That Refresh Your Living Room Instantly

Swapping pillow covers is one of the easiest ways to refresh your living room.

Instead of one large bouquet, group multiple smaller vases together.

Varying heights create visual interest and make the arrangement look designer-inspired.

Small metallic details reflect light and instantly elevate the room.

A little shimmer adds sophistication without overwhelming the space.

This small upgrade makes a big difference in photos.

14. Entryway Styling That Sets the Tone Immediately

Welcome guests with a simple styled vignette near the door.

It sets the tone before they even enter the main space.

15. Floating Shelf Decor Feels Thoughtfully Curated

Use shelves to display small accents, candles, or decorative objects.

Layer items in odd numbers for a balanced look.
