Results of ordering my first piece of fabric from Aliexpress: it's unusable junk :( It was some purple corduroy, and matches what I expected on colour and wale size and stuff, but it's much, much thinner than specified, and it's got damage all over it - not just minor flaws, but big runs and actual holes, like patches of damage the size of my hand, and spread all around the length. I can't see that I'm going to be able to use any of it, except I might be able to piece together a cushion cover or something. Still, now I get to find out what the dispute process is like...
