I have done 12" square muslin quilt "sandwiches" with a different colored thread in the bobbin than in the needle.
Practice what speed works for you. Some people like to go fast, some not so fast- you are moving the quilt so you determine the stitch length. Move to fast and your stitches are long, move to slow and they get very short. It may also need some tension adjusting. That is why the two different colors of thread.
Get some sandwiches made up, put some music on, and go with the flow!
Launie, I did everything as you suggested and I am really busy trying. The machine is doing it's job, but me, not so much. I am bound to get better at it, because it can't get any worse ! There is no where to go but up :)
