Quillters have always made small items either as gifts, or to sell. And after WWII, there were quilting classes in which ladies made small items and lap quilts rather than bed quilts.
Here is a nightdress case that I recently bought on Ebay. It is worked in gold coloured tafetta with a peach inner. It measures 14 x 12.5 inches and is all hand worked.
The edges are hand stitched which is slightly unusual for north country work and makes me think of a class where "the correct way" was taught.
However, the stitching looks so even and well done that it may just be a gift made by an expert quilter. It does not look to have been used.
The seller came from the Tyne and Wear area, and says she does not remember where it came from, but most likely an auction.
