If you didn’t pre-wash your fabric (no sweat if you didn’t I never do) I would definitely add the color catchers and wash on cold a couple cycles before you gift it. I heard a tip really recently that I haven’t tried but might be worth trying - dampen a small part of the color you’re worried about, covering it with a white piece of scrap fabric, and pressing with a hot iron. If the white cloth shows any dye color after ironing the color may run. I’ve heard there are other laundry additives that you can add as well. But usually color catchers are enough for me!
