Invisible Quilting Thread
Invisible Quilting Thread (monofilament nylon) cobweb fine - very soft & pliable. 80s weight.
Available on a small bobbin plus - for the enthusiast - a huge spool of either 25,000m & 68,000 metres.
Larger two spools perform best used under a Dome & Base - a one-off purchase - to control the naturally slippery thread.
