Water soluble thread used for hand and machine basting, machine trapunto, thread auditioning etc. For best results use it in both needle and bobbin. Vanish-Lite disappears with just a spritz of water - use it in your domestic machine with a Topstitch 80/12 needle. Vanish-Extra is a stronger version that can be used in either longarm or domestic machines (with Vanish-Lite in the bobbin), but it requires slightly longer soaking time to fully disappear. Store in a resealable bag in a dry place. And try not to lick the end of it when threading your needle!
