That left a really bare and boring wall and the brown colored curtains were still there too. Boo.
For quite some time I've been looking at murals and different ideas to add some interest. I really wanted something princessy and thought castles might work. I finally found some inspiration for a silhouette/skyline style mural on Modern Parents Messy Kids but for the life of me can no longer find the link to share. So know this idea was not my own, this is just my interpretation of it.
The original mural (which I think you can purchase somewhere) had some Moroccan style buildings. I wanted the background to be more Cinderella's castle-esk so I decided to change the shapes and just googled a few online to give me some ideas.
To get started, I used a regular pencil and just free handed the outline of buildings in London's kingdom. I went this route because I knew I could wash the pencil off the wall if this project went south, meaning I could abort at anytime. It might be hard to see here, but this is really all I did.
