Print off a template for your hearts, I just googled to find a heart image, but here's one. Simply save the image, then resize the image for 3 different sized hearts.
After cutting out your paper templates, pin each one to the felt and cut out your shapes. Do different colors of each shape and as many or as little as you like.
Once you have as much as you'd like, start decorating your wall!
To adhere them to the wall (temporarily), I just used glue dots and stuck a couple along the middle of each heart.
If you don't have any, double sided tape or sticky tack works too.
Kinda fun, huh?
And she loved them! Win!
Have fun! And have a great week!
