The Sewline Air Erasable Fabric Pen makes temporary marks on your fabric. Often when creating you need to make a mark, draw a line or define a space on fabric that is not permanent. When using chalk or a blue line marker is not the best choice, the Sewline Air Erasable Fabric Pen is a great option. Over time (approximately 2-10 days) and without water, the mark will disappear, in high humidity, the marks may not last long! For immediate erasure, a little dab of water will erase the mark immediately.
Always test on your fabric before use, but good for most fabrics.
