Those are my wishes also.. in fact, why is the bobbin so small on a long arm? I went to the sewing fstival here in Denver recently, saw someone demonstration a long arm for a couple, she just happened to be showing the bobbin... I asked why the bobbin wasn't the same size as the thread, makes sense to me.... she just looked at me, and said' it's the bobbin'. Seems that you should be able to use another cone of thread as a bobbin so you have the same amount on both sides...
