I bought some chevron ribbon at Hobby Lobby and it was enough for me to make them for all 5 of my kids. No sewing involved...I literally cut 5 strips of the ribbon about 2ish feet long each. At the top I cut circles out of white yardstick and hand printed their names. I also stuck a bit of pink and red tulle behind the circle and then just stapled it to the ribbon. I picked up a few small command hooks from the store and used these to hang the ribbons on the outside of each of the kids bedroom doors. Next I cut a bunch of hearts out of pink, red, and white cardstock. I have a Fiskars cutter that has a heart stencil so I used that to mass produce enough hearts for the whole time. 14x5 (or however many kids you have).
I make a new ribbon each year so we fill out our hearts and staple them to the ribbon each night. So fun and meaningful!
