Prepare your pallet board by watering down brown paint and covering pallet board. Set aside to dry. You could also leave the pallet board natural.
Cut out a heart shape out of plain paper with scissors. You might need to try several times to get just the right heart. You want a “deep” V in the center of your heart. You'll fill it with yarn, so the deeper the better, otherwise, you'll start to lose your heart shape. You can use our heart template as a guide. Place your paper heart pattern onto cardboard. Trace with a pencil and cut the heart shape out with scissors. Repeat so you have three hearts.
Use the yarn to wrap your cardboard heart. There's no right or wrong way. Wrap in the same direction about three our four times until the cardboard is covered and then randomize the yarn wrappings. Repeat until you have one white, one pink and one red heart, or any colors of your choice.
Place the three hearts onto the pallet board in the position you'd like (horizontal, vertical, straight or angled) and affix with hot glue.
