I bought these hearts at Target after Christmas for .50 cents a pack. I knew I wanted to make a Valentine's Garland, but I also thought they'd work as stencils later. We could also make then into ornaments at some point as well, but for now they are garland hanging in our front window.
I used pink yarn to string it all together and alternated colors. It's a great decoration and the perfect mobile for Baby Brother since his playard/changing table is near the window. And it only took 5 minutes to make and hang up!
