Thank you
For the Hawaiian theme I used eBay for the flower its a alligator hair clip that I just added to the middle of the bow. The palm leaf was a piece of faux leather cut in a craft die and glued and stitched together so it was double-sided. The Deathly Hallows embellishments came from here:-

And fabric was from spoonflower. Most of the character inspired items need a bit of creative searching but they have a few characters there. I just used a test sample size for the bows.
The bunny ears I played with the wire to get the height and just went with it. Headband as from eBay again I got one of the slightly thicker ones. The ears are a little top heavy so I'm going to play with the position of the ears, having wire in them to bend really helps otherwise a bit of fabric on the headband to stop it moving on my head. My hair is too fine to clip the headband to my hair.
This is how I made them in case it helps anyone:-
I did a smaller bit of felt in the middle to pad out the ear and then two piece each side to cover the wire, fabric glued the edge and then went back and stitched it and then stitched the bottom of the felt to the headband.
I had found so great faux fur in grey ages ago and bought a reel of it and I had to go back and match it to the rest of them, think it'll be 3 reels including the tail. I folded it over the edge and stitched it to the felt. I did the same on the back, stitching to the faux fur to join it and also the felt. Then I tidied it up with the little bits on the sides, the base of the ear and between the two ears. I even had to add little extra bits at the back to stop my leopard print duct tape peeking through.
I have no idea how my work friend managed that detail

, when I made my version they didn't have that.
Thank you, I've made a start on the tail and I need to finish the belt and the badge needs tweaking and I think I'm done. Then on to costume two.
