I’ve been quilting quilts withSuperior monopoly invisible thread for years, it is great thread. It is nothing like the nylon invisible threads from years ago that were like fish line. It is not pokey at all, it is just as soft and pliable as any cotton/ polyester thread. It is strong and goes a long way. I use it often for appliqué- even on baby quilts. There has never been any issues with it. You can iron over it, it holds up to laundering- the biggest problem with it is…it’s invisible- hard to see when quilting with it. I do use a regular thread in my bobbin- often * bottom line* or a 60 wt Aurifil.
