A few of us on the forum were trading ideas last year, and I got inspired to go all in on the living room windows. Instead of full-on lights, I went with layered Christmas window decorations from a set I found at quotemywall. They had these elegant snowflakes and baubles that looked almost etched from outside. Guests were asking if they were painted on. Took minutes to apply, zero mess, and the whole vibe shifted instantly.
