This is perfect if you don't have a lot of time, but want to decorate your house for Valentines Day. It was very easy to make, but it looks really nice.
NOT MY ORIGINAL IDEA - PEOPLE HAVE DONE THIS BEFORE
To create this Valentine Heart Garland I used:
-A printed heart shape to trace
-Different shades of pink, white and purple paper
I traced the heart shape onto the different colored papers, cut them out, taped them in random order onto the yarn string, and hung it up, sticking the ends of the yarn onto the top of the door.
Optional: different shapes, different paper colors, make more/less to make a longer/shorter garland, hang it up on your mirror, window etc.
