Could sun bleaching my finished project help even out minor dye lot differences?
Making a shirt and I bought new yarn for it, all from the same dye lot. I had one ball of the same color already from a previous project and accidentally used that one mid way through the project but didn't notice until now when I'm almost done.
It's 100% cotton yarn and it's nominally the same color, it's just that the old ball was slightly lighter. Would laying my shirt out in the sun for a few days, turning so front and back have even coverage, be a way to even out the color? I'm fine with it being a lighter color overall as long as it's the same color overall.
