Wigs Best yarn for wig making?

Yarn is an amalgamation of short threads spun together. You will only get a limited length and the rest falls out. Check Mozekyto's tutorial like you linked for making yarn wefts. They tie down strands and brush it out.

100% acrylic is used most often while the others I am unsure how they fare.

I have had luck softening yarn with fabric softener.

 

100% acrylic always. I personally don't make wefts, so I use really thick yarn (like 4 size) that I find ends up brushing out a tiny bit better than a thin standard size. Brand wise, I use the Lion Brands Hometown a lot for this, but really as long as it's 100% acrylic and you either do the wefts or use a thicker yarn, it can hold a decent amount of length.

 

Thirding that it has to be 100% acrylic - even using a mix with the smallest percentage of wool was terrible to handle in my experience. It really is a hit or miss brand-wise, though! Some brush out nicely* and some are only fluff, no length, and there is no way to tell when looking at the skein just try a couple of different ones and you'll probably find something you like more

*By "nicely" I mean you still brush away ca 50% of the product but at least the wefts stay at a decent length/thickness after.

 

I've had most successes with bulky yarns, I find that fiber length is usually higher for those compared to thinner yarns. It also tends to be a little more cost effective.
100% acrylic is easiest to handle as it's all the same fiber and behaves consistently and predictably.

 

Echoing everyone else about the particular fiber to use, but also: it's really important to somehow anchor the yarn so that it doesn't just tear apart. In those tutorials I believe they tie it to some sort of plastic mesh, but I personally just put a few strands together and knot them in the middle, then brush out both sides. This way you're left with at least half the volume to make the wefts out of.

Unfortunately, no matter what, you're definitely going to lose a lot, though. Again to echo what others have already said, bulkier yarns tend to yield more fiber in the end.

 

I'm not an expert, but since my experience, yarn is easier to smooth if it is made up of 4 threads or 5. You can check this only by undoing it with your fingers. You can also check that it is strong by pulling one of them. There are 100% acrylic yarns that fall apart too easily, just by pulling with your fingers. Before, I was only guided by the beautiful color, but it is very important that the yarn lasts, since you are going to comb many times, brushing and iron it.

 

Personally I prefer using alpaca/wool, human hair and feathers. Human hair is a bit to figure out, but the result worth it and feathers make for very stunning artsy wigs. If youd prefer to stick with mozekytos style and technique Id opt for alpaca. Its pretty and damn worth it. You wont stop touching rhe wig I promise haha (also getting alpaca on etsy or online is not too expensive, or at least justifyable imo)

 

@JJ3_dolls For alpaca, its usually better to simply buy the fibers loose rather than spun as yarn. That is not quite what the thread is about, though. There are other threads about making wigs with loose fiber and with roving, the search function can probably dig them out for you in no time.
