Sew the cotton through both braids above the hair elastic until you are satisfied that there is enough cotton to support the hair if the hair elastic should defect from the hair. Although not mandatory, we suggest leaving the hair elastic in place at this point to avoid the braid becoming loose.

Cut the cotton from the needle. Form a double knot as close to the hair as possible. Repeat this step 2-3 times. Cutting excess cotton from below the knot is a safeguard in case the hair elastics should become caught or snap.

Find the point in the hair where you would like your next weft to sit and section. Above the ears is usually a suitable spot. When you section, take care to leave enough hair around the hairline to cover the band from the weft

Above the section you have just created on the top of the head, secure the hair (taut but not uncomfortably) with a hair clamp. Use smaller hair clamps around the head to keep wispy strands of stray hair clear from falling down whilst you are braiding.

On the section of hair you have just worked on repeat steps 5-15 of this guide. It is completely ordinary for the braids to feel tight initially, but refrain from applying too much tension against the scalp as this could lead to hair damage and could cause traction alopecia.

If required, add a third braid lower down at the nape of the neck. Enough hair should be left to conceal the band on the weft.
While holding the weft extensions, measure along the braid from one side to to another. Double the weft over and cut.
Repeat the last step for each row of braids that you apply. Ensure that the weft is always doubled over. (There are some weft extensions that do not need to be doubled over. Use your expertise and practicality to determine whether your client falls into this category.)
Thread the cotton through the curved needle and tie a knot at the end. Once again, cut off excess cotton below the knot.
Begin at a side that you feel more comfortable sewing. Hold the weft extension band on top of the braid and thread the cotton through both the braid and weft extension. You should repeat this a couple of times until satisfied that the weft extension is secure and taut.
Still holding the weft against the braid and using a sewing technique known as a ‘blanket stitch’ (If you are uncertain about this, familiarise yourself with the method prior to the treatment)
sew along the braid until you reach the end.
To ensure that the weft stays attached to the
braid, sew over the ends as many times as you
feel necessary.
