Well, it's fine if I sew aon the med speed, which is what I usually do. But the high speed still makes loops this morning. I emailed the seller and they said too much oil will cause tension issues. I'm going to change the thread when I get home and see what happens, otherwise I'll take the baby in to see them this weekend. Ugh.
The directions do say to oil, but yes, one drop. Sigh!
Thanks!
