Months ago I began a tutorial (of sorts) on how to reroot a dolls hair
http://www.mariahomedecorations.com/2012/03/re-rooting-dolls-part-one.html which for some reason I never finished so its about time to!
If you take a look at my previous guide (above) I was just at the stage to begin rerooting. A dolls hair had been removed and the new hair was ready to be inserted so I'll continue from there.
2) A tricky part when you are starting out rerooting is figuring how much hair to thread into the needle to fill each hole. Add to this, the existing holes on the dolls head are usually different sizes so you will have to change amounts to suit each one. Some of the hair types (nylon, saran etc.) are different in thickness. You will get used to this very quickly. Seperate some hair and thread it through the needle just as you would in sewing.
The needle is then pushed through a hole in the dolls head. I do this from the outside in.
You will get used to how much hair to put into each hole very quickly. It should slide in easily and should fill the gap nicely (not too bulky or too thin)
Tie a small knot and then trim the end. When I first started I think I added about three knots to the end of each piece in case the knot would come loose but this just makes for a lot of bulk inside the head. So a small knot is enough.
Part three to follow soon.
I hope this was useful!
All the best,
