Here is the wall of my bedroom (forgive the quality of my pictures).
I painted the wall in red and prepared the stencils of the birds and branches.
Honestly I didn't draw them, I searched the shapes online, printed them and traced them on transparent paper. This is the way I prepared my stencils and after cutting out the drawings, they were finally done! :)
I sticked them on the wall once at a time with paper tape and painted on them with black acrylic.
This is the result and I must admit that I am very proud of it!
