Here is an early homemade mitt from 1890-1900's. As with most Folk Art styles, it is one of a kind and this one a beast at 12" diameter. It seems to have been made by someone who knew what they were doing but were short on materials. The back is pieced together similar to the look of the "Decker patent" design. The arrow head wrist strap and sewn-on glove pattern are pretty cool.
The front has that really antique shape.
The front has this narrow piece of leather sewn in at the top possibly because there was not a large enough remnant of leather to cut out the face in one piece or was simply not cut accurately in the early stages and had to be adjusted. The perimeter banding is slit in the space between the thumb and body of the mitt to add more padding as needed. Two rows of holes on either side of the slit are used to lace the mitt back up.
The heel shows the same two rows of holes but was never slit between to add padding. The mitt maker cross-stitched short lengths of leather together to make up the perimeter banding. It is one of my favorite features on the mitt.
The top of the mitt has two straps that are laced and cinched together to create a rudimentary pocket. Welting was added to the edge seams of the mitt to stiffen it up and keep the shape. The edge seams are very stout at 1/4" thick.
