what is the consensus on invisible 'thread' here? i want something clear or smokey. i don't want it to break if someone sits on the bed, so it needs some stretch, but i want it to return to it's original length. i don't want it to break in the longarm needle.
has anyone used any? did you use nylon or poly? what brand? where did you get it? what did you use in the bobbin? is it hard to wind on the bobbin or does it pull too tight?
i like a 40-weight on the longarm and the clear stuff i've seen is thin, so i have questions about it's serviceability. is it so hard to work with that it's simply not worth it?
