I am new to quilting so I tried every kind of marker to find what worked best for me and the fabric I was using. I settled with the pounce and white chalk. It took a few "pounces" with my hand to the applicator to produce enough chalk to mark, but once the applicator was "ready" marking was easy. As I tried so many pencils and markers that proved difficult to get rid of, I was very, very pleased when the chalk ironed off, just as the label stated. I use the white chalk even on unbleached muslin. I have ordered the "barely blue" chalk to make working on the unbleached muslin a little easier. I will let you know.
