I think this will look great on a cardigan.
By the way- that cardigan came from a thrift shop for 25 cents!! I was excited about that find.
Here's a quick little how to on the brooch:
Cut flowers from coordinating felt with a die. Layer and glue them together. Embellish each flower. I sewed the beads on the petals and center of one. I glued the earring to the center of the other. (Remove earring back with wire cutters first.) Glue both flowers to felt and cut out so it doesn't show from the back. Glue pin backs on the back. Quick and easy!
