To get started, you need to cut out some hearts from and old thrift store book. I used a craft punch, which was super fast, but you could just cut them out by hand too.
Once the hearts are all cut out, add some watercolour to just a few. I like pink for Valentine’s Day, but you could do red, or any colour to fit your decor, or wedding, or nursery colour. When one side is dry, be sure to flip the heart over and do the other side. Painting both sides of the hearts will help keep them from curling up, and also make the garland pretty from both sides.
Next, once the paint is dry it’s time to stitch the hearts into a garland. Just feed the paper hearts through your sewing machine just like you would with regular fabric. To create the spaces just run the machine for a second between feeding the hearts in to create the gap. Try and your gaps as even as possible.
