vegan waxed thread

Well, we were going to Art Ellis today so I could look for waxed thread in the shade of green I require, but then it hit me that it's probably waxed with beeswax, which I would normally just ignore, but seeing as this is a vegan cookzine, uh, I should be fastidious.

So then I was researching vegan waxed thread online and found nothing, and then I thought, well, I could find some vegan waxed floss and use that, but people are arguing over which floss is actually vegan, and I got overwhelmed.

So I guess I'll just use my regular cotton thread and hope the knots don't come undone. Any ideas?
