Hi, It sounds to me like you might have a little bur on the needle (a sharp bit that is sticking out)
and sometimes it grabs the fabric and pulls it through so that the colour is showing on the other
side. If not, it could be a small bur on the hook and base (the round thingy that houses the bobbin)
and it is catching the thread as it loops around the bobbin thread to form a stitch. This only needs
to be minute but will need to be filed very carefully until it is quite smooth. Good luck with it - you
don't want to have to buy a new hook and base, they are a bit expensive and hard to find. A very
fine nail-file might be enough and fine sandpaper to finish it off. Be very gentle. Fingers crossed.
A small sharp bit sticking out would catch the thread and take it to the other side causing the other
colour to show. Good luck with it. lol Gleniveve
