I just got my Baileys home quilter, a week ago now. I find it difficult to remember to put the foot down and when I did that it left a big mess on the back of the quilt and jammed it almost every time, it was frustrating. When I first put the bobbin case together, I tried to put it together wrong. Make sure after you put the round fork part in, then put the next piece with the flat side out, I was trying to do it the opposite way and remember to put the pin-like raised point in center and the other 2 sides, move the flaps over top of the raised pin-like areas. When you put the bobbin in it clicks into place. I have finished my first quilt now, didn't do any fancy work, just stitched in the ditch. I have it on my bed and am very happy with my quilt I finished. My husband likes it too.
