I am teaching teens fine arts: they are on a journey to create life messages in art on a hoodie- They'll be using these fabric markers (and lots of others) as part of their personal supplies. I have taught this class before and we used Sharpie markers.... but the hoodies can never be washed as some of the colors bleed. That's a big heads up to use this brand. Fabric markers should not bleed....that's kind of the point. These did not- So thanks! Good product- I recommend
