I, personally use these all the time especially when I was embroidering the leaves on the Garden of Roses quilt. I found that they stayed long enough for me to have adequate time to embroider the veins on the leaves and were very easy to remove any excess markings. Never left any permanent markings on the designs which was very nice!
