I used to be a Connecting Threads thread user but am not for my Lizzie anymore... Have you looked at Glide? I now use Glide from
www.BobbinCentral.com and haven't looked back. Glide is awesome and lint free... and very reasonably priced.
If it weren't for the lint, I'd still use CT thread.. but then I don't remember if I actually ended up using the spool of Essential that I got. I know that their regular thread makes Large Marge cough up lint balls lol
