A set of 2 Iron-off marker – the best for marking! Now you can feel free to mark as clearly as you like! Just iron the marks off after you are done! Can you believe it?!
It doesn’t matter what colour you use. As long as you don’t use a marker the same colour as your fabrics, it doesn’t make a difference whether you use blue or purple on your white fabrics: all will be ironed off! Try it!
Caution: marks reappear below zero degree – you can iron that off again if you after you store the quilt in freezer. Easy rinse is enough to remove the marks – meaning, no marks reappears on ironing after rinse.
Whether the marks will ruin your fabrics, no one can tell. If your quilt are stuck together by glues and can’t be washed, you may not want to use it. If your quilts are stitched together to stand one wash at least, you should be fine.
