True oilcloth is made from woven natural cotton fibers that are treated with oil, usually linseed oil. This process makes oilcloth waterproof and stain resistant, which makes it a great material for tablecloths and aprons.
I’ve found several online resources over the last few years that carry oilcloth.
Probably my favorite is Oilcloth International.
On their site, you can find free downloads for project ideas, cut and sewn products, and a gazillion swatches.
These are by far my faves:
Other places I like to peruse:
Mendel’s Far Out Fabrics also carries oilcloth. And also has a good section on their site about caring for and using oilcloth–although it isn’t “true” oilcloth, it is vinyl adhered to woven cotton fabric, as most oilcloth available today is.
Reprodepot is another great source.
I was immediately in love because I am in love with oilcloth. I’m smitten with oilcloth, actually.
