I use any water erasable I can find. I find that my marks have spritz off for me to iron. I do wash finally as well.
I have 2 friend , one who wrote her label ready. For quilting next day. When she got up couldn't find her writing on a label.
The other friend marked her quilt ready for quilting the next day. You know the rest.
I personally used one had dinner at a class and had to remark so not my favourite, stick to water erasable.
