C’mon, stop stringing us along.This has been a really informative "thread" on this topic.

Trying to find one like der MicroMeister described. It was braided and apparently soft and flexible.Sorry to keep stringing you along but here goes:

Not too expensive, depending on your cost point.
Surprised I didn't think of this sooner, since my wife has tons of it hidden somewhere. Beading line. It has to be small, tough, and flexible. It says it's braided, it looks and feels like Kevlar.
The good news is that you should be able to find it at any craft/beading store. The bad is that calling anything 'beading' really jacks the price.
Wow! Not Kevlar. Hold a match to it and it evaporates like smoke in the wind. Flame ran up it so fast it might be a reasonable alternative for fuse. I thought it might set off the whole spool.
Leaving this here so no one else is tempted to try it.
Edit: That's funny, I just noticed it's called 'Fireline' and the color is 'smoke'.

Thanks John. I have followed some other suggestions and gotten the cotton embroidery thread (looks like what Odd’l Rockets sends with their kits) and it looks like good stuff.VCP You are so right! Most of the newer Fishing lines are Spectra Microbraids which are all very heat sensitive. I've tried SpiderWire, ProBraid, and several Burkley brands with the same Instant Poof results.
I did a little more digging looking for the 2-strand Kevlar thread. here's what I came up with. Scientifics Direct no longer carries the spools DEEEEEEERATS!
however www.thethreadexchange.com has two products that should do the job. I'm not sure if the 6lb is one or two strands but the 14lb has been told to me to be 2-strand.
1: Kevlar Size 23 (tex 21) .006" dia. 6lb test Natural yellow #Kev023natloob 1/2oz spool = 780yds @ 11.00
2: Kevlar Size 46 (tex 40) .008" dia. 14lb test Natural yellow #Kev046natloob 1/2oz spool = 312yds @ 8.00
Since I haven't seen these threads other then the websites photos I can't say for sure if these threads are or will be as soft as the 13lb stuff I have but both above are more than sufficient for LPR rocket chutes. I'd use the 6lb for chutes up to 30inches and the 14lb for larger. also the 6lb stuff looks like it should get softer as it is used.
Hope this helps a little.
Is this the same stuff? SUPER-TEX-40-CRAQ-SPUN-KEVLAR-SEWING-THREAD-1-000-YARD
Maybe only a lifetime supply for a single family.
I found the spool that I have been using recently, actually a blend of 75% polyester, 25% cotton, Coats and Clark, Button & Craft, Dual Duty Plus, several colors are available. If you are using a plastic bag chute, that would melt long before this thread would burn, still have to use appropriate wadding.

Here's another good shroud line thread at a reasonable price:

Why not use kevlar thread?
multistrand Kevlar thread works out well, although it is probably overkill for plastic parachutes. Anything that would burn through cotton thread would likely melt a plastic chute anyway.Yeah, I didn't read far enough back before I posted. My bad. I already have a bunch of kevlar thread so I thought of it.
100% Polyester melts FAST.
Use the cotton covered Polyester button & carpet thread.
