I located the cotton I bought 4m of around 2 years ago. It's a tightly woven cotton, with the stripes about 1.5cm or 5/8th inch wide. There's plenty and I thought it would be useful for 20th century underpinnings.
I also have pale putty green canvas that I got for an edwardian corset - might use it for the denim 1890-1910 corset in Salen's book. I've scaled that pattern up already, but don't think it's suitable for this sew along.
