Okay I might be overloading you with Valentines. But this one is so easy its unbelievable.
Just take your wallpaper. I had some leftover from another project. Trace out your hearts and cut out.
Then just paste on, mine was pre pasted so I just put some warm water on them and applied. See I told you it was easy.
You could also use scrapbook paper or contact paper from the dollar store. here is a link to some contact paper that is similar to my wallpaper above.
Thank you for stopping by and God Bless!
