Create a heart stencil out of paper or cardstock. Place on top of cardboard and cut out two heart shapes.

Cut 2 inch wide strips of cardboard

Attach 2 inch strips to heart shapes with tape. I used scotch tape but wish I would have used packing tape. Bend and curve the cardboard to heart shape.

If filling the heart, fill with toys, candy, confetti, notes, or whatever else you would like to include.

Tape the second heart on top to close the box.

Cut 1.5 inch felt pieces and cut fringes along the length. Start at the bottom section of the heart and add rows to cover the entire heart.

Add additional rows of felt fringe down the sides.

Finish it off by snipping edges off the fringe so it separates the pieces a bit. This helps them to not lay completely flat and look more 3-dimensional. Use hot glue to stick down any pieces that don't look right.

Cut out letters from cardstock using a digital cutting machine - I used my Cricut Explore Air two (my favorite tool in my craft room). Cut out any phrase you would like!

Glue letters onto the heart.
