I made a theme one year which was inspired by a mamas and papas Christmas stocking. I embellished it myself and the theme was a mush of artic/scandi/northern lights/fairytale.
Colours were: deep navy, mint green, powder blue, lavender, white, silver, and ashy wood.
Textures were: wood, sparkles, fur, wool
Objects/motifs were: snowflakes, trees and things made out of wood, stars, antlers, deer, bears, foxes (wooden or white), birds.
My most favourite theme ever, but I also love a red and white version and the rest of my family prefer it, so it was ditched. I still have some decs and plan to find a space to make just into that theme!
