Yes - proper cork is gorgeous to sew with. It cuts beautifully, sews well, is waterproof etc etc
I have my eye on some pearlised cork but won’t buy it until I see the perfect project. It isn’t cheap but is cheaper than real leather and comes in more finishes etc.
This cork is more highly patterned and is the cheaper, thinner kind (think the difference between quilting weight cotton and thin poly-cotton).
