WonderFil’s Thread Tamer spool holder helps to control your thread and spools in three ways. The Vertical Drawing position eliminates tension change and prevents slippery thread from
unreeling. The Perpendicular Drawing position eliminates self-induced ravelling from horizontal drawing and is ideal for cop-sized spools. The Couching and Cording position holds up to three
spools in place to prevent undesired tangling. The Thread Tamer stands alone and can be used with any machine or even while hand sewing.
