Honestly, if you have to ask how to build it, then you shouldn't be building it.
If you were asked about ohms law and battery safety, could you answer it without googling it? Be honest, if you answer no, don't even build a coil with it.
Also, what device are you using? That's not smart to do on some devices, and a lot of regulated devices don't go that low. 0.1 is never the "right ohm" for a beginner, which you seem to be. If I'm wrong tell me, but I would bet on you being a beginner.

Specifically, why are you wanting to wrap it with a resistance so low?
What battery/mod are you using?

No meter?
Any Idea how hard to heat 20ga?
Any Idea how slow it cools?
I would hate to see a BOOM in your future.
Vape wisely.

Really, I mean really? Yesterday was a post about 22awg, and now again the the New Members Section 20awg?? Who is advising anyone, beginner to advanced to use these gauges of wire? Not to sound like the nanny in the house, but really, 20awg is not a gauge of wire to be playing and experimenting with on a single battery mod, mech or regulated IMO, on a series regulated like a Sig150 or IPV3 maybe, or a parallel dual battery mod. Only people I can see that would want to use this type of wire in Kanthal A1 or Nichrome would be cloud competitors which is the very advanced category.
I'll add to what everyone is saying above me, 24 or 26awg largest, just getting started rebuilding I'd suggest 28 or 30awg until you get into good practice, as though I've been rebuilding for going on 2 years, 20 and 22awg scares me, one messed up wrap on a coil and you could be way below your battery safety specs of maximum continuous discharge rate

What mod are you using, what batteries do you have and how many watts do you plan to build for?
It's all about the details
Hi and welcome to the forum.
I have been building coils for about a year and a half, which probably isn't that long compared to some of the people telling you not to do this, and I have never built one that low. Mainly out of safety concerns, but also because even below about .7 or so the vape is too hot and not enjoyable. I do also want to keep my face, It isn't much to look at, but it is mine and I want to keep it relatively intact. Just please rethink the very low subohming hobby, but if you continue DO YOUR HOMEWORK. Be an expert in battery safety and coil building before you attempt this. Really not trying to be preachy, just advice to another vaper.

Not a sub-ohm vaper or anything but an electronics tech and at .1 ohm I consider it a short circuit look for the blown fuse and try to figure out what caused the failure. Just sayin'.
Got a tugboat box with tug rda . I like a lot of smoke that's why I'm trying to go low I feel if I go up to .5 it's gonna not give me Lot of smoke
Well doesn't matter what you build, you're not going to get any smoke. [HASHTAG]#notblowingsmoke[/HASHTAG] ...
You can get just as much vapor at 0.5 ohms. I could compete with your 20g on an iStick 50w and tugboat v2 RDA with twisted 28g at 45 watts. Plus 0.10 ohms on the Tugboat RDA? That's going to be ridiculous hot when you vape it. There isn't that much airflow in it.

Do you value your hand, face, and home?
A coil at that resistance (ohm) will have over a 40 amp draw. There are no 18650 batteries available higher than 30 amps. Using any battery at that resistance in a mechanical mod is courting disaster.
When it comes to coil building, THERE ARE NO SHORTCUTS TO KNOWLEDGE.

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway
Before making any type of coil build, you need to EDUCATE YOURSELF on Ohm's Law and learn about battery specifications. Get an ohm reader, never fire a coil without first measuring its resistance on a metering device. 0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway

Wrapping 20 gauge isn't hard at all lol I did a twisted 20 gauge single coil at .15 ohms . My vape shop said I can run .08 on my tug but not gonna tKe the chance tho gonna go get some 22 gauge and go for .20 build I just got my tug box 3 days ago I had a tug mech befor the box the splatter one
Do yourself and everyone in the vaping community a favor and never go in that shop again. They are on the edge of criminal negligence by telling you that you can actually build that low and be safe.
Edit: the only way you could possibly get away with wrapping that low is if you had at least 2 batteries each rated for 30A in parallel. Even then, you aren't leaving a whole lot of overhead for battery safety. On top of that, your rda is going to be way too hot and probably melt the insulator in a hurry(meaning a potential dead short, meaning a probable battery vent regardless of how many batteries you have in parallel)
