You did a real good job on the re-hairing

i always do mine quite thick if the hair is going to be kept down. If i plan to syle then i do it pretty thin ^^
I dunno if anyone uses this method but what i do is get a bunch of hair, thin it or bulk it out and make sure its double the lengh that i want the hair to be. I tie a knot about half a cm away from the middle and put a fair amount of glue on it and keep it tightly knotted in my hand until is a lil more dry. I keep doing the same thing over and over with other hair strands until i have quite alot. When they all dry i get one of the strands, tie a knot about half a cm away from the original knot and repeat with glueing. When dry i cut in the middle and then have 2 plugs ^^
I widen the plug hole with a safety pin and then use a curved needle and fishing line. I loosely fold the line in half, thread though the needle so there a loop one side and pull the needle through making sure the line ends are on the outside of the plug (obviously i take the safety pin out first hehe) i then loosely slip the hair through the loop and pull the line back through the hole with the hair. It may be a round the houses way of doing but it gets the job done and theres no risk of the hair coming loose ^^
