Here is a quick tutorial on how to make your own felt heart brooch.
You will need:
Some felt cut into two heart shapes(I used 2mm thickness, but you can use thinner), polyester stuffing, lace, needle and thread, a glue gun and I brooch pin.
Attach the lace to the cut out heart shapes. Use a blanket stitch to attach the two sides of the heart. Leave a gap for stuffing. Glue the brooch pin to the back of the heart. Stuff the heart with polyester stuffing. Close the gap with some more blanket stitching and TA DA!!!
