I was looking at markers to use in a table runner class. I have used the blue Clover markers without any issues.
The package warns to remove markings completely within 2 weeks. It also says to NOT IRON before markings are removed.
I have a new to me pounce to try. It is white and supposed to disappear with heat. Some people are putting this in a empty chalk o liner to use to mark reference lines when longarming. I haven't tried it yet.
