Interesting thread-about thread! You got some interesting comments that are also useful to the rest of us. I especially appreciated feline fanatic's comments. I tried the Invisiline 100 this past weekend to STID. It worked beautifully and I think I will go back and buy some more colors. I liked it in the bobbin also. I like to make samples that reflect thread and batting choices. There are so many combinations and so many results. Thank you for your thread.
