Antique Memonite hand made seat cushion sewing Lancaster Pennsylvania stump work

Description

Antique hand made colorful Menonite seat or buggy cushion.
The detail and colors are great. The cushion is about 16" square and 4" thick.
There is a 5" long opening to one side seam which needs to be resewn.
I believe this was made in the 1930's or earlier.
I have been told that this type of handiwork is called "stumpwork"?
