Do you need to change the tesion for the difference in the weight of the thread? I know that I have to do this sometimes on the longarm. I haven't had any problem with embroidery, but it is a thought.
I really like Isacord but it is very expensive here. Where do they have it more reasonable?
Also, I thought Isacord came out with a set of just a few varigated thread. I could be wrong it has been quite awhile since I was in the store, maybe they changed their minds. I am just not sure.
