Thanks Judy!
I was worried about quality. You know the old saying "You get what you paid for!" I want a good deal on thread but not if it harms the finished product. After spending a lot of money on a serger and also on fabric, doesn't make much sense to buy poor quality thread. But, buying 4 spools at a time can get very pricey if I buy from the LQS.
I figure I need a set of light thread and a set of dark thread to get started.
