If you have a sewing machine, this Valentines decoration is easily made, and my kids really liked the project!
Just potato-stamp hearts on paper; I used plain brown craft paper but you can use any sort really, even newspaper. No need to be perfect here, my 2-year-old had quite some production going. (If you stop the project here you have made yourself some lovely and very romantic wrapping paper!) Cut the hearts out, and sew them into a bunting. My machine had black thread in it and I didn’t bother changing it; I think it actually looks quite nice like this. Make sure to leave some thread at the ends for attaching!
My daughter’s bed looked lovely instantaneously! (The wallpaper bird is from Inke.)
