All you need the felt pencil toppers is some scraps of felt, some embroidery thread and a needle and a thin black permanent marker.
Cut the scraps of felt into heart shapes, you need two hearts per pencil.
Sew around the edges with the embroidery thread. Alternatively you can glue the outer edges together with some fabric glue! leaving a gap at the bottom for the pencil to insert.
Then invite your kids to draw on their little heart faces – happy, goofy, confused….. they decide!
