I've made this medieval gown I'm adding rabbit trim to. I've sewn some on the cuffs but the way I did that wouldn't work for the areas I've marked here. All guides I've found online have been for faux fur. Can anyone give me some insight? I'm mostly unsure on how to make it stay flat. Should I add small stitches all the way round or sew it the whole way round? I ofc want it to look as clean as possible. Most of the rabbit furs I have are relatively thick compared to the usual. I'm hand sewing.

Can anyone enlighten me on what the intention is with these giant bit rings are for? I unfortunately don't understand what he's saying and no help in the caption. I've seen big-ish rings on polo ponies but nothing like this.
