Sometimes I look at things and see something that's ... off. Other times I can look right at things and not see them at all.
I'm glad you caught that. I really did not want to take that tension apart.
Now I have to decide to stick with using a substitute needle that I can only get in size 11 and 14, or reset the needle bar for 15x1's. There's not a lot of leeway for altering that needle bar.
