I got some ridiculously cheap stretch denim today. It’s the usual dark navy colour that will run more than some formerly great rivers are today. But like those rivers, it won’t run forever, though it may take a rather long time before it runs only to a negligible amount.
I’ve been told I can wash it to death in hot water, then soak in cold with vinegar, and also with salt, to help set in the remaining colours after that.
But would it ever be set enough that I can sew it with a white denim in a garment?
What about other light fabrics that might resist the denim’s colour running? There must be some that isn’t the waterproof rainwear stuff. Even if it’s a heavy polyester.
And what about white embroidery on denim? Would those threads get stained?
I basically don’t want a dark denim garment, and want to contrast it with something light. What are my options?
