The construction:
I made the top layer from cream silk taffeta. I attached the thumb and made the wrist slit. Then I turned under all raw edges and top stitched them with herringbone stitch. I top stitched also the thumb seam.
Then I made a similar leather lining, just without the pointed tip, and whip stitched it to the silk around all edges. Then I closed the wrist slit by fagoting.
I lined the tip with blue silk taffeta and closed the side seam by fagoting and they were finished.
The finished mitt inside out.
