I'm doing something wrong with my Brother CS 100.
It hums along quite well with straight stitching, but for a
zig zag it pulls up the bottom threads and the color
shows up on the top layer.
I read the manual when I first got it a couple of years
ago, or at least I intended to. Lost it and will most likely
have to go online to see if I can find one there.
Otherwise it is a good machine, sews tightly with the
zig zags but it only bothers me when I use a different
color in the bobbin. Which is a different one from my Singer,
darn it. I know I"m using the correct bobbin. I'm sure of that.
Any ideas?
