Most efficient method of tying roe bags?

[MichaelAngelo]

My grandfather had an old spawn sac tying tool. It's all gummed up. Short of degreasing it and regreasing it, what's your favourite way of tying spawn sacs?

So far, I've been laying 6 nettings on the table, putting 2-3 eggs in each one, and tying them up with spider thread. Not using any tools.

Then clipping the tops once I'm done of course.
