Question for you all about plain red fabric --how many times do you wash it before you use it to prevent bleeding colors?
I usually wash once and put a white rag with it so I can see if it bleeds (and I do this with all bright or dark colors, not just red, I've actually had more trouble with turquoise bleeding than red). If it bleeds, I put it in the sink and soak it in water with about a 1/2 cup of vinegar overnight, do a rinse and spin in the washer and then try again with a white rag (that will take out "loose" dye. If it still bleeds on the second wash I pitch it. I'm not messing with chemicals and I'm not taking any chances on it bleeding on other parts of my project or any other clothes.
