I have a APQS Freedom machine and I love the connecting threads cotton thread. I like that it is a 50 wt. so it does not have such a heavy look to it when I do not want the thread to be so visible. I also used it when I had my Tin Lizzie and it also worked just fine on that machine. It is nice that they sell smaller spools of thread so I am able to stock up on many of their colors to have on hand. I just quilted a T shirt quilt for someone last week and I used 8 colors on it and luckily I had all the colors I needed in my Conneting Threads supply drawer. i ahve not tried their Polyestor threads as I prefer to use the cotton threads.
