Multiple threaded needles

I am still not sure about my current experiment but it is at least giving me an opportunity to practice the technique of keeping a few needles threaded and switching between them to sew small sections at a time.

It makes mistakes easier to identify before they become a major problem but the difficulty is to make sure that the threads don't get tangled up in each other. You end up having to 'park' needles in strange places to make sure that the thread doesn't pass behind an area that you are going to want to use.
