I use all of Connecting Threads on my long arm. Used it on my streched Juki 18" before that. The cotton threads do lint a lot but since I clean out my bobbin area with every bobbin change it doesn't bother me. Just clean, oil and go. Only thing I don't like about CT's threads is they keep discontinuing certain colors then bringing them back under another name but with the same code number. I made a chart of all their threads I have and noticed a few sure looked close to another color by a different name but then noticed their code number was the same. Nothing like keeping us on our toes.
