The twill tape is applied to each raw edge of all fur pieces in the overhand stitch manner.  Above, the twill is then turned under and catch-stitched to the skin.
Below left, you see the interlined coat with the completely stitched  fur collar and lining waiting in the background.
Above is stitched collar receiving the wool fill. 
The inside edge of the collar has been catch-stitched to the raw edges of the neckline of the coat with the lining in place. 
The outside of the collar's edge will now be eased and catch-stitched in place with heavy thread that was used when stitching the inside of the collar edge to the coat.
