You know, it's full of floss, some hoops maybe some patterns and fabric or even a half finished project and it's priced at, like $1. You might start to swoon over all those yummy colors but then hesitate because you are uncertain if the old floss is dye-fast. Here is the good news: you don't have to pass it up.
So, how do you know if it's dye-fast? Well, I took the paper off mine, laid it on some white cotton fabric, folded the fabric with the floss inside and ran it under water. I gave it some squeezes and let it be for a few minutes and then unfolded it.
You can see that this beautiful blue turned out to be just fine because no dye was on the white fabric. So, I let it dry and now I can feel confident using it. This lilac skein though.... definitely not dye-fast.
But now I know that this problem is easily solved with the help of everybody's best friend - white vinegar.
