You will need 14 pieces of crafter's felt (the pieces should be big enough to be hooped in a 4" x 4" hoop), satin ribbon and fiberfill for stuffing.
Embroider the designs on 7 of the felt pieces.
Make a heart pattern out of paper. Place it over each design, trace and cut along the line to get a felt heart with the design at the center.
Place the felt heart face-up onto another piece of felt. Attach with pins and machine stitch close to the edge. Leave a small opening at the top of the heart.
Cut around the edges of the heart to remove excess backing.
Stuff with fiberfill through the opening (use a pencil or tweezers if the openning is too small).
Cut out 7 lengths of ribbon about 6" long. Fold each into a loop. Insert the raw ends of the loop into the opening and machine-stitch the opening closed.
