I do that all the time for sewing on my smaller & vintage machines. All of my thread these days is on big, cross-wound cones, and instead of dragging a cone holder around with me and using the big cones, I just wind a few bobbins and use those on the littler machines instead. Less stuff to drag around with me is good!

How you 'get' your thread to the needle should not be a problem, whether it is a normal spool, a bobbin or even a cone sitting in a cup next to the machine. It is the upper tension that will determine how the thread works. Even though some spools are wound in different ways and should be on the different spools (topside or sideways), for most folks, it still works to have all threads on top.

I do it all the time to use up bits on the bobbin. go for it.

I do this all the time.....use up the bobbin threads and put it on the spool pin and I make sure there is a felt circle and all the bobbins I have, I been used for double duty for them. Uses up the thread.

OMG! I never, ever thought of doing this! Learn something new every day.

I do that all the time. I recently finished a quilt and had about 6 inches of thread left.

I'm with Lynnie; I've don it for years.

Same here too
