I use it sometimes, but most of the time, I go with "normal" thread - invisible seems so fragile for some reason - I do tend to use a decorative stitch for the quilting..I figure its going to show, so it might as well be something neat that is showing....I love the scollop to do quilting with,....if your machine has a stitch that is a zigzag with several stitches on each side of the zigzag, you can make it wider and increase the stitch lenght to about 3 and it will give you a nice scollop.....try playing with it......
