When we moved in my daughter asked for her room to be painted pink and purple. She's 4 and is in that phase.. I wasn't feeling the pink and purple love so I decided to order a decal set from etsy. I scoured around and found a beautiful set of trees from Urban Walls. I'm so pleased with the result!
Have you tried wall decals? I'm most happy with how graphic the black tree trunks looks against the wickham grey by Benjamin Moore. (Colour inspired by this post at Posie Gets Cozy!!)
This was a lot of pieces to cut apart, place, rub, and peel. So glad I had family to help!
