I've been ordering from Connecting Threads for about a year and a half, and am very surprised at the comments that their fabrics are not good quality. ALL of the fabrics I have received are very, very nice. They don't feel like they are mostly sizing with a little fabric thrown in. I have to say that I've bought LQS fabric that didn't seem to match the quality of the fabric I ordered through Connecting Threads. I have also gotten to where I only use their Essential Threads.
I think it may be that how each of us defines 'quality fabric' might have slightly different criteria, based on our past experiences and intentions for that fabric. There are no wrong answers.
