I prefer my gingham to be true vintage 100% cotton. This fabric has a more supple, much nicer hand than gingham available to us today. Vintage gingham can be found on Ebay and many online fabric shops. I would deal with a seller with a proven background in vintage fabrics. The apron below is home sewn, about 60 years old with silver color rick rack and white chicken scratch embroidery.
Till Later,
Cathy
