Step 1: Collect Materials
Materials you need are some sort of white fabric (be it some socks or even sew together your own ears), a hat (in our case a fedora), pipe cleaners if needed, glue, sewing supplies if you need extra support for your ears, and a hot glue gun.
Step 2: Pipe Cleaners
Step 3: Make the Ears
Step 4: Situate Them on the Hat
Step 5: Glue Them Onto the Hat
you now have your bunny ear hat. :3
