Making trim for the coat was the final touch before I packed it up and sent it off. I was using the drapery fabric that we had used on some of the other costumes.
I had to make a "furry" cuff as well as trim the the collar and make some small pompom like puffs.
For the cuffs, I started with a bias tube of the plain white fabric, pressed flat, to act as a base to sew on. I cut a wide piece of the drapery fabric and folded it accordion style then cut into the edges randomly.... Folded it in half, offsetting the edges a bit, and then gathered it along the folded edge.
I laid a piece of this on the bias tube and stitched it down. Next I laid another gathered piece on the first, with the folded edges just overlapping. To fill in the middle I took a single layer of the cut edge drapery fabric and gathered it down the middle. This was laid in the middle and stitched down to the bias strip.
