Theyve made smaller machines with no bobbin, they sew a chain stit h

I wind a bunch ahead of time. It's still a pain to change them out, but at least I don't have to wind them mid-project. :)

DH keeps asking me why we don't have them.

My hubby likes to re-engineer things as a hobby. He's currently playing around with different ways of machine quilting and has dissected a few thrift store machines in his quest. I told him if he could come up with a way of having an "endless" bobbin, we'd be millionaires.

I looked at superior bottom line and will order some. On the website it talks about special needles for thinner threads. Can I use the regular needles I have or do I have to use the special ones?

I use my regular Organ 80/12 with no problems.
