I've just written a post about one of my latest finishes, Asian Stack-n-Whack. Its lovely reds, yellows and navys needed a quiet thread just to add a bit of texture to the quilt and to hold the layers together.
I used WonderFil Specialty Threads' Master Quilter to achieve the look I wanted. I use MQ#52, Dark Blue instead of MQ#49, Navy because I did want the quilting to show a bit, but not too much.
Master Quilter is a 40wt 3ply polyester thread. The thread has been cottonized, that means that the thread has passed through a heat process that reduces the stretch in the thread and gives a matt finish.
The thread will blend beautifully as it looks more like a cotton thread than a polyester thread. The thread is available in 72 solid colors.
