Guess it depends on how much leave-out you want/need. I watched a youtube vid on how to do a "spider weave", coined by stylist Jehan, but the girl who did the vid did say she was modifying the technique, but it does allow for versatility and parting just about anywhere along the front without seeing any tracks.
The size of your head will determine the fullness with this method. You begin by sectioning off the perimeter/leave-out portion. Then you section the hair across the middle (ear to ear) to separate the front from the back.
Then where you placed your leave out, you will braid a two corn rows as small as you can make them around the leave out section and the ends will be sewn down later in the install..
Next you will pick a side of the front to work on and begin braiding corn rows straight back. This is where it gets moderately tricky dependent upon how skilled you are at doing sew-ins.
Whichever you start on, the first braid that you did around the leave out will serve as the first "leg" of the "spider" hence why the method is referred to as the spider method. The next thing you do is section off a pic of hair maybe about a finger width apart (again dependent on how wide your finger is and how thick your hair is), the idea is to make sure that this section is large enough so that if parted down its middle, it would be enough to cover any tracking.
After sectioning off this piece you will pin it back with something and then make another part. This part WILL be another cornrow or "leg"straight back, and again it should be as thin as possible. You will continue this until the both sides of the front are completed.
My head is small so I completed the front with 6 braids on one side of my leave out and 4 on the other side. I have an off centered part for leave-out. My hair is moderately thick.
But anyway the back section of your hair can be braided any way that you like. I braided my back in a circle, because I use a net to keep the braids flat and secure. I braided the ends of the front cornrows into the circle braid to create a flat base.
To sew, I started from the back going up in a u-shaped pattern using a loop and hook sew method. Once I got to the lowest braid that connected to the front cornrows, I started cutting the tracks . ( thats the downside to doing it this way if you dont like to cut the tracks).
I doubled the tracks on each cornrow that was connected the front braid.
I did this until I achieved the desired fullness.
Again I said I have a small head so I was able to achieve this look with just about 5.5-6 oz. I can do high ponytails, deep side parts, twists etc with this method.
Downside(s): in my opinion if you dont want to cut tracks this isnt the method for you
you have to maintain your natural hair so it wouldn't be ideal if you have completely different textures to blend as you would constantly be manipulating your tresses to create a flawless blend. =HIGH MAINTENANCE
Upside: if you dont want to use alot of weave you could possibly save money on that end,
looks VERY natural if you dont mind the work involved
I will update this with pictures to let you know how mine looks...and I will find the vid link from where I learned this method..its a long vid..just like this post is long..SRY but I hope this helps...
Other ideas would be to try sewing on a lace wig??? Or U-part since there is usually more hair more closely placed.. you could also try a net and just have someone sew the tracks REALLY close,but keep in mind you may get excess tangling ;
goodluck in your search..again in my effort to be thorough, I went on long..sorry for the long post
