For small applications only. It says it lasts for 24-48 hours but it really only lasts for 8 hours at the most. If you're using this for larger applications you better be a quick seamstress. Definitely not for quilts. Also it does not come off with a damp cloth, it only intensifies the ink before making it disappear even faster.
Although this pen does tend to disapear quickly, I love it! The only thing that bothered me was that, when ironed over, it does not disapear at all.
WONDERFUL! I could not live without this item! Worth every penny!
I used this pen to mark a quilt pattern on a quilt I was quilting. It disappeared so quickly that I had to mark and quilt - mark and quilt. Although I love the disappearing characteristic, it vanishes too quickly for large applications.
