I just read every reply to this question. I just got a long arm less than 2 weeks ago and have a few different brands of thread "to try out" on my long arm. So I found everyone's comments here interesting so it gives me some direction also in what brands I should try on my long arm. With thread being expensive, I am hoping to find a couple brands that work well on my brand of long arm (Tin Lizzie) and then I can just stick to using those brands.
